Week 8 - Challenge 3 - Coin Holder Design

Class A Draft analysis

First considering the direction of the cavity and plane surface on the class A surface, the z axis is selected as the tooling direction. The axis is supposed to pass through the point at the centre of the base surface of the class A surface. A line is constructed in z axis passing through this point. This line is selected as the tooling axis .

Using the above selected tooling axis, the draft analysis of class A surface is performed. Analysis result shows that all the surfaces have fairly much larger angle than 3 digree which is the nominal draft angle. The screenshots of the analysis result is given below

Final Part draft analysis

The draft analysis is conducted on the final part with tooling axis as reference. All the surfaces are greater than 3 digree which is nominal draft angle. So the part is manufacturable. The screenshots of the analysis result is given below.
