Week 8 - Challenge 3 - Coin Holder Design

TREE STRUCTURE :

CREATION OF TOOLING AXIS :

extract the class A base surface, and create a point with (0,0) co- ordinates.

then create the line on the one side with reference to the drafted two points. and again the same procedure for another side.

using the line command, bisect the two lines to form a centre line and name it as the tooling axis.

the line which pass through the mid point of the two line segement is known as the bisecting lines.

CREATION OF DRAFT ANALYIS IN CLASS A SURFACE :

draft analysis is the major important role of design check which show the design can be manufacturable with the required tooling direction.
for an plastic product design, there must be a minimum draft angle of 3 degree.

after the creation of tooling axis, open the draft analysis command using insert - analysis - draft analysis.
set the axis system in the line of tooling direction.
then draft angle for this product is analysized.

CREATION OF CLASS B SURFACE :

the class B surface is created by using the extract of class a surface. in this case, the fillets are avoided, to make ease of designing.
the class B surface is created with the offset 2.5 mm
while creating the fillets in class B, if the class B is under the class A then the fillet value will be ( fillets + material thickness )
if the class B is above the class A then fillets value will be ( fillet value - material thickness )

CREATION OF CLASS C SURFACE :

the class C surface is created by using the extract of class A surface where it is swept along the adjcent surface to get the desired output.
as the inner face is cleared with the core and outer surface will get cleared with the cavity
the C surface is created perpendicular to the tooling axis.

after that join class C surface with Class A surface. then trim (A+C) with B. to get the desired output.
atlast go to part design , go to insert - surface based feature - closed filled surface.
to get the final closed thickned plastic product.
