Week 9 - Attachment Feature Creation (Ribs & Screw Boss) - Challenge 1
RIBS AND SCREW BOSS
Tooloing Axis creation:
- In this coin holder challenge, I have not used the bisecting method to create the tooling axis.
- Firstly analyze the given component in which direction tooling axis will be suitable.
- Then extract the base surface from the given class A surface.
- Then create a point in the centre of the extracted surface using 'on the surface' option.
- Next create a line normal to the extracted surface that passing through the created point and consider the line as Tooling axis.
Draft Analysis:
- Draft analysis is done on the class A surface and the final surface component.
- Normally the draft angle for plastic surfaces ranges from 1/2 to 3 degrees.
- I have given the maximum positive draft angle for plastic surface is 3 degree.
- The results of the draft analysis on class A and the final components are as below.
