Week 8 - Challenge 3 - Coin Holder Design

Report on draft analysis and tooling axis creation

Draft is provided to a plastic component so as to avoid the difficulty in retracting the cavity mould after injecting the plastic into the cavity.

The minimum draft to any plastic component should be 3 mm.hence the Class A surface of Coin Holder is analysed for a draft.

The given class A surface consists of four walls at an angle to the base,and the angle found was >3° to the vertical after performing draft analysis.

Tooling axis creation

1.Insert a point on the base of the Coin Holder

2.Insert an axis system on the point of extracted base.

3.Only the four wall surfaces are nearly parallel to tooling axis and other surfaces are apparently >3 degrees the tooling axis is drawn perpendicular to the base.

after performing the feature draft analysis along the tooling axis the surface was found to be meeting the requirements of the draft.
