Week 8 - Challenge 3 - Coin Holder Design

COIN HOLDER

• To set up the class-A surface and create a tooling axis
• add draft angle
• To create a base surface of the model
• To create a B-surface
• To create a C-surface
• To use a close surface command to create a solid part model

TOOLING AXIS

Tooling axis can be classified into two methods

• direct method

1. For this model, use a line at the mid-point of the base of the coin holder
2. Due to perpendicular walls of the class A surface

DRAFT ANALYSIS

• To analyze the class A surface using the feature draft command
• Next in his command, the compass was set on the tooling axis and the draft angle was set at 3 deg.

CLASS A

THE GAP BETWEEN THE CLASS A AND B SURFACE IS 2.5MM IN THICKNESS
