Sa se deseneze piesa din figura 2, utilizand straturile


Sa se deseneze piesa din figura 2, utilizand straturile

Se stabilesc cinci straturi, si anume:

startul linie groasa: tip linie - Continuous; culoare - rosie; grosime - 0,35 mm;

stratul linie subtire: tip linie - Continuous; culoare - negru; grosime - 0,09 mm;



stratul axa: tip linie - Dashdot; culoare - verde; grosime - 0,09 mm;

stratul hasuri: tip linie - continua; culoare - Cyan; grosime - 0,09 mm;

stratul cote: tip linie - continua; culoare - Blue; grosime - 0,09 mm;

Stabilim strat curent: stratul Axa, si trasam axa de simetrie a piesei.

Command: Line

Specify first point: 50,148.5

Specify next point or [Undo]: 250,148.5

Specify next point or [Close/Undo]: enter

Modificam stratul curent in asa fel incat stratul Linie groasa sa devina strat curent, si desenam conturul piesei.

Pentru a lucra mai usor mutam UCS din punctul curent in punctul de coordonate 55,148.5, adica la intersectia dintre suprafata frontala din stanga a piesei si axa de simetrie a acesteia.

Command: UCS

Current UCS name: *World*

Enter an option [New/Move/ . .] <World>: m

Specify new origin point or [Zdepth] <0,0,0>: 55,148.5

Se schimba stratul curent pe stratul Axa, pentru a desena cele doua axe corespunzatoare gaurilor de M10 si apoi desenam axele respective.

Command: Line

Specify first point: 55,-20

Specify next point or [Close/Undo]: @0,40

Specify next point or [Close/Undo]: enter

Command: Offset

Specify offset distance or [Through] <0>: 120

Select object to offset or <exit>: P1

Select point on side to offset: P2

Select object to offset or <exit>: enter

Pentru trasarea celor doua gauri de M10, vom considera ca gaura inainte de filetare are φ8. Se trece stratul curent pe stratul Linie groasa.

Command: Line

Specify next point or [Close/Undo]: enter

Se trece stratul curent pe stratul Linie subtire.

Command: Line

Specify first point: 50,10

Specify next point or [Close/Undo]: @0,-25

Specify next point or [Close/Undo]: enter

Command: Mirror

Select objects: w

Specify first corner: N1

Specify opposite corner: N2

Select objects: enter

Specify first point of mirror line: D1

Pentru a desena si cea de-a doua gaura folosim comanda Copy.

Command: Copy

Se ingheata straturile Axa si Linie subtire si apoi se hasureaza cu comanda Bhatch, prin indicarea unui punct in interiorul zonei de hasurare. Se trece startul Hasuri ca strat curent.

Command: Bhatch - apare fereastra de dialog Boundary Hatch.

Din aceasta fereastra se modifica:

pattern: ANSI 31;

Pick points - se stabilesc trei puncte pentru cele trei zone interioare de hasurat (K1, K2 si K3).

Dupa dezghetarea celor doua straturi, inghetate inainte de hasurare, avem desenul de executie al piesei, mai putin cotele.
