Week 8 - Challenge 3 - Coin Holder Design

Here it is given a coin holder plastic component Class A.

I created Class B, Class C and Tooling Axis.

It is defined as the direction in which the mould/core and cavity open. Selection of the direction of the tooling axis depends on the ease at which components can be easily ejected.By analysing the component the most easily ejectable direction is somewhere close to the Z direction,(might be inclined to it) so we have made a sketch on the YZ plane of Axis System) to create a bisecting line considering the 2 faces which might be difficult to be tooled.

Class B:

First step is to create the side wall surfaces by extracting the required surface from Class A and untrimmed it thus we will get a single surface which will be extrapolated to get the required size and finally offset it to the inner side of class A as per the thickness of the material and trim them together and apply the required fillet by measuring the values from class A.Base surface of the component is then extract, untrimmed, extrapolated, offset and trimmed.The top walls can be directly extrapolated from the extracted surfaces and offset it for the required size of the material.Then join the base, side wall and top wall by trim operations.

Class C:

C surface has been created from the boundary lines of class A surface and by extracting the supporting surfaces then sweep the boundary lines with reference to the extracted surfaces.
