• din puct de vedere al informatiilor un desen include:<br />
– informatii geometrice (marime, forma, aspect)<br />
– relatii functionale<br />
– tolerante care sa asigure o buna functionalitate a pieselor<br />
– materiale acoperiri de protectie<br />
– informatii de documentare (codificare,varianta revizuita etc)<br />
• Un desen <strong>ing</strong>ineresc trebuie sa defineasca complet o piesa<br />
• Fiecare specificatie trebuie sa poata fi masurabila<br />
• Desenul <strong>ing</strong>ineresc afecteaza toate diviziunile organizatorice<br />
ale intreprinderii<br />
• Desenul <strong>ing</strong>ineresc are un impact major asupra costului<br />

Exactitatea desenelor<br />
• Inexactitatea desenelor poate conduce<br />
la pierderi de timp si energie:<br />
• timp pentru corectarea erorilor din<br />
desen<br />
• pierderi de material<br />
• timp de lucru<br />
• incarcarea inutila a masinii<br />
