COTAREA IN DESENUL TEHNIC&lt;/div&gt;
&lt;div style=&quot;text-align: center;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; Cotarea este operatia de inscriere pe desen a dimensiunilor necesare pentru fabricarea si controlul obiectului respectiv.&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&amp;nbsp; Regulile de executie grafica a elementelor cotarii folosite in desenul industrial, respectiv forma, dimensiunile si dispunerea acestora,precum si clasificarea cotelor sunt cuprinse in SR ISO 129 : 1994.&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; ELEMENTELE COTARII&amp;nbsp;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp;Elementele cotarii sunt: linia de cota, liniile ajutatoare,linia de indicatie, cota.&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&amp;nbsp; &amp;nbsp;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&amp;nbsp; &amp;nbsp;&amp;nbsp;&lt;b&gt;&lt;i&gt;Linia de cota -&amp;nbsp;&lt;/i&gt;&lt;/b&gt; este linia deasupra careia se inscrie cota respectiva si este prevazuta, la ambele extremitati, cu sageti sau combinatii de sageti si puncte.&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&amp;nbsp; &amp;nbsp;&lt;b&gt;&lt;i&gt;Liniile ajutatoare -&amp;nbsp;&lt;/i&gt;&lt;/b&gt; indica punctele sau planele intre care se prescrie cota, ele putand construi si la construirea punctelor necesare pentru determinarea formei geometrice a obiectului reprezentat.&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&amp;nbsp; &amp;nbsp;&lt;b&gt;&lt;i&gt;Linia de indicatie -&amp;nbsp;&lt;/i&gt;&lt;/b&gt; serveste pentru a indica pe desen elementul la care se refera o prescriptie, o notare conventionala sau o cota,care din lipsa de spatiu nu poate fi scrisa deasupra liniei de cota .&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;b&gt;&lt;i&gt;&amp;nbsp; &amp;nbsp;Cota -&amp;nbsp;&lt;/i&gt;&lt;/b&gt; reprezinta valoarea numerica a dimensiunii a elementului cotat, inscrisa direct pe desen sau printr-un simbol literal, in cazul desenelor care cuprind tabele de dimensiuni.&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
Cota poate fi precedata de simboluri, cuvinte, prescurtari, necesare pentru precizarea elementului cotat.&lt;/div&gt;

&lt;div style=&quot;text-align: left;&quot;&gt;
Extremitatile &lt;b style=&quot;font-style: italic;&quot;&gt;liniei de cota&lt;/b&gt; pot fi :sageata, bara oblica sau punct in cazul in care se refera originea.&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
Sageata este reprezentata prin doua linii scurte, formand bratele unui unghi oarecare cuprins intre&amp;nbsp;&lt;span style=&quot;line-height: 115%;&quot;&gt;15&lt;/span&gt;&lt;sup style=&quot;line-height: 115%;&quot;&gt;0&lt;/sup&gt;&lt;span style=&quot;line-height: 115%;&quot;&gt;- 90&lt;/span&gt;&lt;sup style=&quot;line-height: 115%;&quot;&gt;0. &lt;span style=&quot;font-size: small;&quot;&gt;Sageata poate fi deschisa sau inchisa, in acest ultim caz, innegrita sau nu . Dimensiunea sagetilor trebuie sa fie proportionala cu dimensiunea desenului. Pe acelasi desen se foloseste un singur tip de sageata ce se poate inlocui cu punct sau bara, sagetile se executa la extremitatile linii de cota.Cand nu exista spatiul suficient, sagetile pot fi dispuse in exteriorul linii de cota. Pentru cotarea unei raze, linia de cota are o singura sageata ce se sprijina pe linia de contur.&lt;/span&gt;&lt;/sup&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;sup style=&quot;line-height: 115%;&quot;&gt;&lt;span style=&quot;font-size: small;&quot;&gt;Varful sagetii se poate sprijini fie pe interiorul, fie pe exteriorul conturului elementului.&amp;nbsp;&lt;/span&gt;&lt;/sup&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;sup style=&quot;line-height: 115%;&quot;&gt;&lt;span style=&quot;font-size: small;&quot;&gt;Linia de cota cu o singura sageata se mai intalneste si la cotarea pieselor simetrice reprezentate jumatate vedere jumatate sectiune. Sageata poate fi inlocuita cu o bara oblica trasata cu linie subtire si inclinata la&lt;/span&gt;&lt;/sup&gt;&lt;sup style=&quot;line-height: 115%;&quot;&gt;&lt;span style=&quot;font-size: small;&quot;&gt;&amp;nbsp;&lt;/span&gt;&lt;/sup&gt;&lt;span style=&quot;text-align: center;&quot;&gt;45&lt;/span&gt;&lt;sup style=&quot;text-align: center;&quot;&gt;0&lt;/sup&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;sup style=&quot;text-align: center;&quot;&gt;&lt;span style=&quot;font-size: small;&quot;&gt;Punctul de origine este reprezentat printr-un cerc cu&amp;nbsp;&lt;/span&gt;&lt;/sup&gt;&lt;b&gt;Ø = 3mm neinnegrit.&lt;/b&gt;&lt;/div&gt;

Daca este necesar, ele pot fi trasate oblic, dar tot paralele intre ele.&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
Liniile ajutatoare depasesc cu 2... 3mm liniile de cota. Ca linii ajutatoare pot fi atat liniile de contur, cat si liniile de axa.&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
Liniile ajutatoare se pot trasa radial, in cazul cotarii dimensiunilor unghiulare. Liniile de constructie concurente, precum si linia ajutatoare ce trece prin intersectia lor trebuie prelungite dincolo de punctul lor de intersectie.&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp;Ca regula generala, liniile ajutatoare si liniile de cota nu trebuie sa se intersecteze intre ele sau cu alte parti ale desenului .Asadar, cotele se dau in ordine crescatoare de la piesa spre exterior, cu o distanta convenabila intre ele ( minim 5 mm ), astfel incat sa fie usor de citit .Deasemenea pe piesele reprezentate in sectiune, cotele referitoare la exteriorul piesei se scot pe o parte a proiectiei, iar cele referitoare la interiorul piesei pe cealalta parte a piesei.&lt;/div&gt;

&lt;div style=&quot;text-align: left;&quot;&gt;
&amp;nbsp; &amp;nbsp; Linia de indicatie este linia continua subtire, terminata cu sageata pe elementul la care se refera. Se utilizeaza pentru a indica pe desen o prescriptie, o notare conventionala sau o cota, care din lipsa de spatiu, nu poate fi inscrisa deasupra liniei de cota.&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;

&lt;div style=&quot;text-align: left;&quot;&gt;
&amp;nbsp;- &lt;b&gt;&lt;i&gt;cote nefunctionale ,&lt;/i&gt;&lt;/b&gt; - cote care nu sunt necesare pentru functionarea piesei, dar sunt necesare pentru executia acesteia&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&amp;nbsp;-&lt;i&gt;&lt;b&gt; cote auxiliare,&lt;/b&gt;&lt;/i&gt; - sunt cote care se refera la dimensiuni cotate informativ. nu au rol hotarator in functionarea piesei sau in executia acesteia si decurg din alte valori date pe desen ( cotele auxiliare se dau in paranteze )&lt;/div&gt;

&amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp;Dupa criteriul geometric :&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&amp;nbsp;&lt;b&gt;&lt;i&gt;- cote de trasare,&lt;/i&gt;&lt;/b&gt;&amp;nbsp;- se refera la o dimensiune ce trebuie determinata geometric prin trasare, in vederea realizarii piesei,&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&amp;nbsp;&lt;b&gt;&lt;i&gt;- cote de prelucrare,&lt;/i&gt;&lt;/b&gt;&amp;nbsp;- inscrise de regula pe desenele de operatii si se refera la o dimensiune limitata fie la o suprafata de referinta si o muchie taietoare a sculei fie de doua muchii taietoare ale sculei.&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;b&gt;&lt;i&gt;- cote de control,&lt;/i&gt;&lt;/b&gt;&amp;nbsp;- se refera la o dimensiune limitata de o suprafata de referinta si un reper al instrumentului de verificare.&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; INSCRIERA COTELOR&amp;nbsp;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp;Valorile cotelor se inscriu pe desen cu caractere suficient de mari pentru a se asigura o buna vizibilitate atat a desenului original, cat si a reproducerilor. Valorile cotelor trebuie plasate in asa fel incat sa nu fie intersectate de alte linii de pe desen. Valorile cotelor sunt dispuse paralel cu linia de cota, deasupra acesteia, astfel incat sa poata fi citite de jos in sus sau din dreapta desenului.&amp;nbsp;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
Pentru cotarea unghiurilor si arcelor se aplica aceeasi regula, considerandu-se directie a liniei de cota, coarda corespunzatoare.Se admite scrierea dimensiunilor unghiulare paralel cu baza desenului, daca aceasta contribuie la claritatea desenului.&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: center;&quot;&gt;

&lt;br /&gt;
&lt;br /&gt;
&amp;nbsp; &amp;nbsp; &amp;nbsp; Cand cota se scrie pe o suprafata hasurata, se intrerup in dreptul cotei, dandu-i-se golului o suprafata aproximativ circulara sau dreptunghiulara.&lt;br /&gt;
&amp;nbsp; Daca mai multe linii de cota paralele sunt taiate de o axa in mijlocul lor, cotele se scriu alternativa in stanga si dreapta axei.&lt;br /&gt;

&amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp;Inscrierea cotelor trebuie adaptata situatiei, astfel incat se pot inscrie:&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;

&lt;div style=&quot;text-align: left;&quot;&gt;

&lt;div style=&quot;text-align: left;&quot;&gt;
- pe sau la extremitatea unei linii de indicatie, atunci cand extremitatea opusa se termina pe o linie de cota prea scurta pentru a permite inscrierea valorii.&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
- deasupra prelungirii liniei de cota, atunci cand spatiul nu permite inscrierea valorii prin intreruperea unei linii de cota care nu este orizontala.&lt;/div&gt;

REPREZENTAREA SECTIUNILOR&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&amp;nbsp; &amp;nbsp; &amp;nbsp;Prin &lt;b&gt;&lt;i&gt;sectiune&lt;/i&gt;&lt;/b&gt; se intelege reprezentarea in proiectie ortogonala pe un plan a obiectului, dupa intersectia acestuia cu o suprafata fictiva de sectionare si indepartarea imaginara a partii obiectului, aflata intre ochiul observatorului si suprafata de sectionare.&amp;nbsp;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&amp;nbsp; &amp;nbsp; &amp;nbsp;Prin &lt;b&gt;&lt;i&gt;suprafata se sectionare&lt;/i&gt;&lt;/b&gt; se intelege acea suprafata cu ajutorul careia se taie imaginar piesa in locul in care este nevoie sa se evidentieze configuratia interioara a acesteia. Suprafata de sectionare poate fi formata din&lt;b&gt;&lt;i&gt; una sau mai multe suprafete plane&lt;/i&gt;&lt;/b&gt; sau &lt;i style=&quot;font-weight: bold;&quot;&gt;dintr-o suprafata cilindrica&lt;/i&gt;.&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&amp;nbsp; &amp;nbsp; &amp;nbsp;Urma suprafetei de sectionare pe planul proiectiei poarta denumirea de &lt;i style=&quot;font-weight: bold;&quot;&gt;traseu de sectionare&lt;/i&gt;. Traseul de sectionare se reprezinta cu linie punct subtire, avand la capetele traseului si in locurile de schimbare a directiei segmente de dreapta trasate cu linie continua groasa si care sa nu intersecteze liniile de contur. Perpendicular pe segmentele extreme ale traseului se reprezinta sageti cu coada subtire si cu varful sprijinit pe segment, indicand directia de proiectie. Segmentul de capat va depasi varful sagetii cu 2 - 3 mm.&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;b&gt;&lt;i&gt;Traseele de sectionare&lt;/i&gt;&lt;/b&gt; se noteaza cu litere majuscule inscrise in paralel cu baza formatului deasupra, respectiv, langa linia sagetii avand dimensiunea nominala de 1,5 - 2 ori mai mare decat a dimensiunii nominale a scrierii de pe acelasi desen. Deasupra reprezentarii sectiunii rezultate se vor scrie literele de la capatul traseului.&amp;nbsp;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&amp;nbsp; Suprafetele rezultate din sectionare se hasureaza conform STAS 104 - 80. Conturul sau muchiile unor elemente ale obiectului aflate in fata planului de sectionare se pot reprezenta cu linie punct subtire, daca reprezentarea acestor elemente este necesara pentru intelegerea formei si daca nu creeaza posibilitatea de confuzie.&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;

RAPOARTE SI LINII UTILIZATE IN DESENUL TEHNIC&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; Scara este raportul dintre dimensiunea liniara a reprezentarii unei piese de pe un desen original&amp;nbsp;&lt;/div&gt;
si dimensiunea liniara reala a segmentului corespunzator obiectului insusi.&lt;br /&gt;
&lt;br /&gt;
Scarile pot fi:&lt;br /&gt;
&lt;span style=&quot;font-size: large;&quot;&gt;- de marime&lt;/span&gt; : scari ce corespund unui raport mai mare de 1 : 1. Ele sunt cu atat mai mari cu cat raportul corespunzator creste.&lt;br /&gt;
&lt;span style=&quot;font-size: large;&quot;&gt;- scara de marime naturala&lt;/span&gt; : scara ce corespunde raportului 1 : 1&lt;br /&gt;
&lt;span style=&quot;font-size: large;&quot;&gt;- scara de reducere &lt;/span&gt;: scara ce corespund unor rapoarte mai mici de 1 : 1. Ele corespund unor rapoarte cu atat mai mici cu cat raportul corespunzator scade.&lt;br /&gt;
&lt;br /&gt;
&amp;nbsp; &lt;span style=&quot;font-size: large;&quot;&gt;&amp;nbsp;NOTA :&lt;/span&gt;&lt;br /&gt;
Notarea completa a unui raport trebuie sa cuprinda cuvantul ,, SCARA &#39;&#39;,urmat de indicarea raportului ales&lt;br /&gt;
Daca nu exista posibilitatea de confuzie, cuvantul ,, SCARA&#39;&#39; &amp;nbsp;poate fi omis.&lt;br /&gt;
&lt;br /&gt;
INDICARE PE DESEN:&lt;br /&gt;
&lt;br /&gt;
&amp;nbsp; &amp;nbsp; Notarea scarii utilizate trebuie inscrisa in indicatorul desenului. Daca sunt utilizte mai multe scari de reprezentare, celelalte scari diferite de aceasta sunt inscrise langa sau sub notarea proiectiilor carora le corespund.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: center;&quot;&gt;
&lt;a href=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhmBxaL7adCXDjfYJDphXI7oPQwnAI7udC8q-LQ_e0rkH6JBWNBXrKkKtdO4Pmc8dWq2bqdlyJYaKAP0LNxxinjk8gH9GmBPpqt4UmUtRz6doRrDc0ORpES1K8zzwcHZ3945mCZINNMm7a7/s1600/scari.PNG&quot; imageanchor=&quot;1&quot; style=&quot;margin-left: 1em; margin-right: 1em;&quot;&gt;&lt;img border=&quot;0&quot; height=&quot;198&quot; src=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhmBxaL7adCXDjfYJDphXI7oPQwnAI7udC8q-LQ_e0rkH6JBWNBXrKkKtdO4Pmc8dWq2bqdlyJYaKAP0LNxxinjk8gH9GmBPpqt4UmUtRz6doRrDc0ORpES1K8zzwcHZ3945mCZINNMm7a7/s640/scari.PNG&quot; width=&quot;640&quot; /&gt;&lt;/a&gt;&lt;/div&gt;
&lt;br /&gt;
&lt;br /&gt;
&amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp;Scara se alege in functie de complexitatea desenului reprezentat si destinatia desenului respectiv.&lt;br /&gt;
In toate cazurile ea trebuie sa fie suficient de mare pentru a permite vizualizarea si interpretarea usoara si corecta &amp;nbsp;a datelor furnizate. Scara si dimensiunile obiectului de reprezentat influenteaza alegerea formatului desenului.&lt;br /&gt;
&amp;nbsp; &amp;nbsp; &amp;nbsp;Detaliile care sunt prea mici pentru o cotare completa in reprezenatrea principala, trebuiesc reprezenate intr-o vedere de detaliu ( sectiune ) la o scara mai mare, alaturi de vederea principala.&lt;br /&gt;

&lt;div style=&quot;text-align: center;&quot;&gt;
&lt;span style=&quot;font-size: large;&quot;&gt;&lt;b&gt;&lt;br /&gt;&lt;/b&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; Liniile utilizate in desenul tehnic &lt;b&gt;pentru axe, contururi, muchii acoperite, linii ajutatoare, linii de cota, hasuri, etc&lt;/b&gt;., sunt de patru tipuri si anume :&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;i&gt;&lt;b&gt;- linie continua&lt;/b&gt;&lt;/i&gt;&amp;nbsp;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;b&gt;&lt;i&gt;- linie continua intrerupta&amp;nbsp;&lt;/i&gt;&lt;/b&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;b&gt;&lt;i&gt;- linie punct&lt;/i&gt;&lt;/b&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;b&gt;&lt;i&gt;- linie doua puncte&lt;/i&gt;&lt;/b&gt; ,&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&amp;nbsp; &amp;nbsp;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&amp;nbsp;iar din punct de vedere &lt;b&gt;al grosimii&lt;/b&gt; se clasifica in doua clase:&amp;nbsp;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;b&gt;&lt;i&gt;- linie groasa&amp;nbsp;&lt;/i&gt;&lt;/b&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;b&gt;&lt;i&gt;- linie subtire&lt;/i&gt;&lt;/b&gt;&lt;/div&gt;
&lt;br /&gt;
&amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp;Grosimea de baza&lt;span style=&quot;font-size: large; font-style: italic; font-weight: bold;&quot;&gt; b&lt;/span&gt;&lt;i style=&quot;font-weight: bold;&quot;&gt;&amp;nbsp;&lt;/i&gt;a liniilor utilizate in desenul tehnic este cea a liniei continue groase;&lt;br /&gt;
se alege in functie de marimea, complexitatea si natura desenului si se pastreaza aceeasi pentru toate reprezentarile executate le aceeasi scara, pe aceeasi plansa pentru o anumita piesa.&lt;br /&gt;
&lt;br /&gt;
Grosimea liniilor se alege din urmatorul sir de valori date in mm : 2,0 mm, 1,4 mm, 1,0 mm, 0,7 mm, 0,5 mm, &amp;nbsp;0,35 mm, 0,25 mm si 0, 18 mm.&lt;br /&gt;
&amp;nbsp;Grosimea de trasare pentru liniile subtiri este de aproximativ &amp;nbsp;&lt;span style=&quot;font-size: large;&quot;&gt;&lt;b&gt;&lt;i&gt;b/3.&lt;/i&gt;&lt;/b&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-size: large;&quot;&gt;&amp;nbsp; &amp;nbsp;&lt;/span&gt;Lungimea segmentelor si intervalelor dintre acestea trebuie sa fie uniforme de-a lungul aceleiasi linii intrerupte, linie punct sau linie cu doua puncte.&lt;br /&gt;
&lt;br /&gt;
&amp;nbsp; In acest tabel sunt prezentate tipuri de linii utilizate in desenul tehnic, precum si o serie de exemple de utilizare a acestora:&lt;br /&gt;

&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-size: large;&quot;&gt;1. dimensiunile tabelului,&lt;/span&gt; ( a x b ) fig.1&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-size: large;&quot;&gt;2. chenarul formatului,&lt;/span&gt; - delimiteaza campul desenului , se traseaza cu linie continua groasa la o distanta de marginea formatului 20 mm pentru formatele A0 si A1 si 10 mm pentru formatele A4, A3, A2.&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-size: large;&quot;&gt;3.&lt;/span&gt; &lt;span style=&quot;font-size: large;&quot;&gt;Zona neutra&lt;/span&gt;, - este cuprinsa intre marginile formatului finit si chenarul care delimiteaza campul desenului.&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-size: large;&quot;&gt;4. Fasia de indosariere, &lt;/span&gt;- este situata pe latura plansei din stanga indicatorului, in sensul de citire a acestuia si are latimea minima de 20 mm si inaltimea de 297 mm.&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-size: large;&quot;&gt;5. Indicatorul,&lt;/span&gt; - este pozitionat in campul desenului in coltul inferior dreapta al acestuia.&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-size: large;&quot;&gt;6.Repere de centrare,&lt;/span&gt;&amp;nbsp;- sunt segmente de dreapta situate la extremitatile celor doua axe de simetrie ale plansei finite si se reprezinta cu linie continua de minim 0,5mm grosime care incepe de la marginile formatului finit si depaseste cu aproximativ 5 mm chenarul ce delimiteaza campul desenului.&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-size: large;&quot;&gt;7. Reperele de orientare,&lt;/span&gt; - indica sensul de citire al desenului si constau din sageti amplasate pe chenar. Unul din repere este amplasat pe dimensiunea mica a &amp;nbsp;formatului, celalalt pe dimensiunea mare a &amp;nbsp;formatului si coincid cu reperele de formare astfel incat din reperele de orientare sa fie dirijat catre &amp;nbsp;desenator&amp;nbsp;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-size: large;&quot;&gt;8. Gradatia metrica de referinta,&lt;/span&gt; - se recomanda sa fie pe toate desenele. Se dispune de preferinta simetric fata de un reper de centrare si este amplasata in zona neutra, lipita de chenar.&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-size: large;&quot;&gt;9. Sistemul de coordonare,&lt;/span&gt; - este recomandat pentru formatele, in scopul de a permite localizarea usoara pe desen a detaliilor, adaugirilor, modificarilor. Cifrele si literele se scriu cu caractere drepte conform STAS ISO 3098 / 1 si se plaseaza in zona neutra langa chenar.&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-size: large;&quot;&gt;10. Unghiurile de decupare,&lt;/span&gt; - sunt plasate in cele patru colturi ale formatului finit si se reprezinta ca triunghiuri dreptunghice isoscele cu laturi congruente.&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
Plansele de desen vor contine in mod obligatoriu : indicator, chenar si fasie de indosariere ( sau atasata ),&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
restul elementelor fiind faculattive.&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: center;&quot;&gt;
&lt;b&gt;&lt;span style=&quot;font-size: x-large;&quot;&gt;Indicatorul&lt;/span&gt;&lt;/b&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: center;&quot;&gt;
&lt;span style=&quot;font-size: large; text-align: left;&quot;&gt;&amp;nbsp;&lt;/span&gt;&lt;span style=&quot;text-align: left;&quot;&gt;&amp;nbsp;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;span style=&quot;font-size: large;&quot;&gt;&amp;nbsp; &amp;nbsp; Indicatorul,&amp;nbsp;&lt;/span&gt;serveste la identificarea desenului si a obiectului reprezentat si contine datele principale asupra acestuia. Se aplica pe fiecare desen de ansamblu, respectiv pe fiecare din plansele ce il compun.&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&amp;nbsp; &amp;nbsp;Forma , dimensiunile, modul de amplasare si de completare a indicatorului sunt prevazute in&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&amp;nbsp;SR ISO 5457 : 1994.&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&amp;nbsp; &amp;nbsp; &amp;nbsp;Indiacatorul se amplaseza, de regula, in coltul inferior dreapta al formatului, lipti de chenar&amp;nbsp;un exemplu va este prezentat mai jos :&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;

&lt;br /&gt;
&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&lt;strong&gt;&amp;nbsp;&lt;/strong&gt;&lt;br /&gt;
&lt;strong&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; &amp;nbsp;INTRODUCERE&lt;/strong&gt;&lt;br /&gt;
&lt;br /&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;Desenul tehnic este mijlocul de reprezentare grafica a obiectelor dupa anumite criterii,&amp;nbsp;reguli&amp;nbsp;conventionale &lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
si metode adoptate de toti lucratorii dintr-un domeniu de activitate. Desenul adaptat domeniului respectiv a fost folosit de om pentru a exprima pentru sine sau pentru altii o anumita idee tehnica .&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;In&amp;nbsp;realizarea oricarui&amp;nbsp;produs industrial, fie el o piesa simpla sau complexa, un edificiu de constructie sau o nava spatiala, desenul tehnic&amp;nbsp;&amp;nbsp;este prezent, permitand reprezentarea formei, a dimensiunilor, a conditiilor de precizie se de functionare a acestora.&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&amp;nbsp;&amp;nbsp; Prin desen se exprima, se ordoneaza si se sistematizeaza gandirea tehnica,&amp;nbsp; pentru ca produsul ce urmeaza a se executa sa raspunda tuturor cerintelor de ordin tehnic, economic, estetic, etc.&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
Desenul tehnic este reprezentarea grafica plana, la care se folosesc metodele geometriei descriptive si o serie de reguli si conventii stabilite prin standarde,&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
in vederea reprezentarii unor obiecte, suprafete, etc.&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
Aceasta disciplina pune la dispozitia tuturor celor ce lucreaza in tehnica, indiferent de nivelul de pregatire profesionala, metode grafice atat pentru reprezentarea unei conceptii cat si pentru interpretarea ei, in vederea materializarii acesteia .&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&amp;nbsp;&amp;nbsp; Tinand cont de faptul ca proiectarea si executie diferitelor constructii de masini angreneaza colective tot mai largi de ingineri, tehnicieni si muncitori, care in multe cazuri nu se gasesc in aceeasi localitate sau chiar tara , deci se intelege de&amp;nbsp;la sine ca odata cu evolutia industriei tehnice cooperarea in acest domeniu nu ar avea loc .&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;Rezulat clar ca desenul tehnic a devenit un mijloc de legatura intre conceptia si executia tehnica, realizate pe plan mondial .&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
Regulile de reprezentare in desenul avand in majoritatea cazurilor valabilitate generala si pe zi ce trece se tinde spre internationalizare totala.&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&amp;nbsp;Se poate spune ca desenul tehnic a devenit un limbaj tehnic international&lt;/div&gt;
&lt;br /&gt;

&lt;strong&gt;MATERIALE DE BAZA SI AUXILIARE UTILIZATE IN DESENUL TEHNIC&lt;/strong&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: center;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: center;&quot;&gt;
&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&lt;/div&gt;
&lt;div style=&quot;text-align: center;&quot;&gt;
&lt;strong&gt;&amp;nbsp; HARTIA PENTRU DESEN&lt;/strong&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; Coala de hartie este materialul de baza pentru elaborarea lucrarilor.In&amp;nbsp;functie de modul prezentarii desenului si modul executarii, se deosebesc urmatoarele feluri de hartie:&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;em&gt;&lt;strong&gt;&lt;span style=&quot;font-size: large;&quot;&gt;- hartia opaca&lt;/span&gt;&lt;/strong&gt; -&lt;/em&gt; de culoare alba, speciala pentru lucrari grafice , are structura omogena.Este de calitate, daca este elastica si permite stergerea repetata cu guma fara a se scamosa : pentru aceasta hartia trebuia sa aiba un grad mare de incleiere . Acest tip de hartie este destinat reprezentarii desenelor originale,&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;span style=&quot;font-size: large;&quot;&gt;&lt;strong&gt;&lt;em&gt;- hartia de calc&lt;/em&gt;&lt;span style=&quot;font-size: small;&quot;&gt; -&lt;/span&gt; &lt;/strong&gt;&lt;/span&gt;re grosimi diferite si este transparenta datorita tratarii cu o emulsie speciala .&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
se utilizeaza, datorita transparentei, la executarea desenelor duplicate fie direct, fie&amp;nbsp;prin&amp;nbsp;copiere dupa desenul original. Este recomandabil ca desenele duplicat sa fie realizate in tus prin calitatea si claritatea copiilor obtinute prin multiplicare la heliograf.&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;strong&gt;&lt;em&gt;&lt;span style=&quot;font-size: large;&quot;&gt;- hartia heliografica&lt;/span&gt;,&amp;nbsp;( ozalid )&lt;/em&gt;&lt;/strong&gt; - se foloseste la multiplicarea desenelor executate pe hartia sau panza de calc.&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: center;&quot;&gt;
&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&lt;strong&gt;CREIOANE PENTRU DESEN&lt;/strong&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: center;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div align=&quot;left&quot; style=&quot;text-align: center;&quot;&gt;
﻿&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;Creioanele pentru desen sunt de calitate superioara si de tarii diferite .Exista o scara a duritatii pentru minele creioanelor si anume:&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;strong&gt;- mina moale&lt;/strong&gt; : 4B : 3B : 2B : B &lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;strong&gt;-mina semidura&lt;/strong&gt; : F : HB : BHB &lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
In afara de creioanele pentru desen se mai utilizeaza si portminele (pixuri ), care sunt mai eficiente deoarece diferitele grosimi ale minei raman constante ( 1 ; 0,7 : 0,5 ) , in timpul executarii desenului .&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
Varful de mina se ascute &lt;span style=&quot;font-size: large;&quot;&gt;bilateral, &lt;/span&gt;deoarece in timpul lucrului se mentine grosimea de trasare .&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
Creioanele se ascut la forma corecta cu ajutorul ascutitorilor de tip scolar sau cu lama.&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
Varful minelor pentru creioane sau pixuri se mai poate ascuti si cu ajutorul unei bucati de glaspapir fin, lipita pe o placa de lemn.&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&lt;strong&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; TUSURILE PENTRU DESENE&lt;/strong&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;Tusul&amp;nbsp; negru se foloseste la trasarea desenelor tehnice dupa trasarea preliminara in creion a acestora, precum si la trasarea desenelor in duplicat, deasemenea se mai foloseste la elaborarea desenelor executate in tente si la trasarea umbrelor in desenul arhitectual .&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;Tusurile colorate sunt utilizate la alcatuirea diagramelor, a graficelor, de productie, la executarea desenelor de instalatii, a schemelor etc .&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&amp;nbsp;&amp;nbsp; Este de preferat sa se foloseasca tusul ambalat in capsule din material plastic, utilizate la umplerea instrumentelor de trasat. &lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; &lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;strong&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;MATERIALE PENTRU STERS SI CORECTAT&lt;/strong&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;Pentru stergerea, corectarea si curatirea unui desen tehnic se folosesc urmatoarele instrumente auxiliare:&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
lama, guma, sablonul pentru sters, peria.&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;span style=&quot;font-size: large;&quot;&gt;&lt;em&gt;- lama,&lt;/em&gt;&lt;/span&gt; - se mai utilizeaza si la decuparea hartiei cu ajutorul unei scurte baghete de lemn &lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;span style=&quot;font-size: large;&quot;&gt;&lt;em&gt;- sablonul pentru sters,&lt;/em&gt;&lt;/span&gt;&lt;span style=&quot;font-size: small;&quot;&gt; - este din material plastic sau celuloid este utilizat la stergerea unor linii dintr-o anumita zona, protejand in acelasi timp liniile vecine trasate corect.&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
Se aseaza sablonul cu una din taieturile lui deasupra locului de corectat pe desen si se sterge, apoi, cu guma pe intreaga suprafata de corectat, protejand astfel liniile invecinate.&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;

CLASIFICAREA DESENELOR TEHNICE&lt;br /&gt;
&lt;br /&gt;
&lt;div align=&quot;left&quot;&gt;
&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; &lt;span style=&quot;font-size: large;&quot;&gt;Desenele&lt;/span&gt; tehnice folosite in numeroase sectoare ale industriei sunt de tipuri foarte variate .&lt;/div&gt;
&lt;div align=&quot;left&quot;&gt;
Conform STAS 415-80, desenele se clasifica dupa mai multe criterii.&lt;/div&gt;
&lt;div align=&quot;left&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div align=&quot;left&quot;&gt;
Dupa&lt;strong&gt; domeniul la care se refera&lt;/strong&gt; , desenul tehnic se clasifica in :&lt;/div&gt;
&lt;div align=&quot;left&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div align=&quot;left&quot;&gt;
&amp;nbsp;&lt;span style=&quot;font-size: large;&quot;&gt;- &lt;em&gt;desen industrial&lt;/em&gt;&lt;/span&gt;&lt;em&gt; , - &lt;/em&gt;ce se refera , la reprezentarea obiectelor si conceptiilor tehnice privind structura, constructia, functionarea si realizarea obiectelor din domeniul constructiilor de masini, navale, aerospatiale, electronic si energetic, constructiilor metalice in general etc .&lt;/div&gt;

&lt;br /&gt;
Dupa &lt;span style=&quot;font-size: large;&quot;&gt;&lt;strong&gt;destinatie&lt;/strong&gt;&lt;/span&gt; desenul tehnic se clasifica in :&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
&lt;div style=&quot;text-align: center;&quot;&gt;
STANDARDIZAREA&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&amp;nbsp; &amp;nbsp; &amp;nbsp;Dezvoltarea productiei industriale a impus sistematizarea regulilor si conventiilor de proiectare si executare in conditii identice a anumitor elemente sau piese din sectorul constructii de masini sau din alte domenii ale industriei .&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
Operatia de sistematizare a regulilor si conventiilorde reprezentare, proiectare, executare,exploatare si intretinere a masinilor , agregatelor, instalatiilor sau produselor industriale , este cunoscuta sub denumirea de&amp;nbsp;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;u&gt;&lt;b&gt;STANDARDIZARE.&lt;/b&gt;&lt;/u&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
Activitatea de &lt;u&gt;standardizare&lt;/u&gt; se rasfrange si asupra desenului tehnic.Astfel prin standarde de stat se stabilesc forme si dimensiuni necesare pentru intocmirea desenelor, tipurile si grosimea liniilor uzuale.&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
Se stabilesc, de asemenea, normele si conventiile privitoare la asezarea in sectiune a pieselor, precum si la reprezentarea axonometrica a obiectelor .&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
Prin aplicarea standardizarii s-au obtinut rezultate bune in productia de serie , si de masa , prin rationalizarea utilajului, aceasta a condus la reducerea costului si deci la cresterea productivitatii muncii .&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
Dezvoltarea continua a productiei a determinat dezvoltarea schimbului de marfuri pe plan mondial, fapt ce a condus la infiintarea Organizatiei Internatinale de Standarde ( I.S.O. ), &amp;nbsp;care are ca scop imbunatatirea si largirea domeniului de aplicarea a standardelor valabile in toate tarile care participa la aceasta organizatie mondiala .&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
&amp;nbsp; &amp;nbsp; &amp;nbsp;In tara noastra , s-a creeat , in anul 1948, Comisia de Standardizare, care colaboreaza, aproba si difuzeaza, normele si prescriptiile tehnice pentru toate sectoarele industriei .&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
Aceste norme si prescriptii au fost numite &lt;b&gt;&lt;u&gt;Standarde de Stat&lt;/u&gt;&lt;/b&gt; ( S.T.A.S. ),&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;
cele referitoare la desenul tenic fac parte din categoria sectoarelor generale si anume &lt;b&gt;&lt;u&gt;Grupa U 10 .&lt;/u&gt;&lt;/b&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: left;&quot;&gt;

&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&amp;nbsp; &amp;nbsp; &amp;nbsp;Desenul tehnic este reprezentarea grafica a unui proiect , pe baza unor conventii si reguli stabilite in acest scop.&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
Desenul tehnic constituie cel ami potrivit mijloc de legatura intre conceptie si realizarea practica a unui obiect&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
(organ de masina , utilaj , instalatie , etc.).&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
Desenul tehnic este limbajul de comunicare intre proiectanti si executanti utilizat in problemele curente ale productiei .Desenul tehnic este una din cele mai importante discipline, ce fundamenteaza pregatirea personalului tehniccare lucreaza in ateliere, uzine, institutii cu specific de proiectare sau centre de cercetare .&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
Aceasta disciplina este astazi insusita de cei care lucreaza nemijlocit in productie, la mese de trasaj,&amp;nbsp;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
la masini-unelte, la control tehnic, la benzile de montaj, etc .&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&amp;nbsp; &amp;nbsp; &amp;nbsp;Muncitorii din aceste sectoare trebuie sa aiba cunostinte minimale in domeniuul reprezentarii tehnice, necesare pentru citirea si interpretarea desenelor deexecutie a pieselor, planelor de operatii sau a desenelor de montaj.&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&amp;nbsp; &amp;nbsp; &amp;nbsp; Pentru personalul tehnico-ingineresc,desenul tehnic serveste la exteriorizarea conceptiei asupra unui produs industrial, ca, de exemplu mecanism, dispozitiv, aparat, sau masina.&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
Este necesar sasearate ca si celelalte discipline tehnice ce contribuie la pregatirea personalului tehni-co ingineresc folosesc in expunere metode grafice ale desenului tehnic, spre exemplu :rezistenta materialelor,&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
organe de masini, mecanisme, tehnologia prelucrarilor mecanice, etc .&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
In activitatea ce conceptie, de proiectare si de executie in constructii de masini, aceasta disciplina foloseste integral cunostintele de bazadin desenul de proiectii, precum si cunostinte di tehnologia materialelor si tehnologia de fabricatie .&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&amp;nbsp; &amp;nbsp;&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&amp;nbsp; &amp;nbsp;Se poate spune ca desenul tehnic s-a dezvoltat in acelasi timp cu perfectionarea si dezvoltarea industriei .&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
Regulile privind reprezentarea constructiilor de masini, ca, de altfel, a oricaror produse, au un domeniu de aplicare universal.&lt;/div&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
Acest lucru permite colaborarea nu numai intre inteprinderile dintr-un stat ci si o cooperare internationala in domeniul tehnic, stiintific si economic .&lt;/div&gt;
