Week 9 - Project 1 - Door Applique Design with Engineering Features
AIM :
Create TOOLING AXIS, CLASS A, CLASS B, and CLASS C SURFACE AND the HEAT STAKES and the LOCATORS for the door applique.
create a tooling axis.
create class B surface
offset the class A surface.
extrude the boundary of the offset surface.
then extrapolate the boundary with support of offset surface
class B
create class c surface
take the boundary of class A surface.
sweep the boundary with the tooling axis.
join the B surface with A surface
FINAL TRIM
trim B surface with the joined A and C surface.
CLOSED SURFACE
NOW THICK THE ATTACHED SURFACE
4 WAY LOCATORS
inseart a sketch
pad the sketch
chamfer the top edges
and apply fillet to it
copy the part work and paste
transfer the 4 way locator to other side
2 WAY LOCATOR
insert a sketch
pad the sketch
apply chamfer to it
HEAT STAKES
take parallel curve of the boundary
ineart points on it
insert sketch
apply pad, draft, chamfer, and fillet
translate the heat stakes to each points of the parallel curve
CLEARANCE TO HEAT STAKES
Insert sketch
pad the sketch
translate it to each heat stakes
and then remove it from the thickened surface
MULTI-SECTION VIEW
DRAFTING
It is a tool that allows the user to ‘see’ whether the part they are designing can be removed from the tool being used to make it. In the case of plastic injection molded parts it also allows the designer to see if there is enough draft on the part to ensure that it can be correctly grained. I always use the tool with the axis direction method. Put the main axis on the draft direction line with Z being parallel to it. Select the tool then select the part body. You may need to reposition the axis again. The results window has 2 options 1 with just 3 color variants and the other with many variants. They can be edited by double-clicking on them to give you the result you desire. The colors show the different draft angles
