Week 8 - Challenge 6 - Core & Cavity Design

AIM:

• To create a core and cavity of the given switch bezel component.
• To create parting surface and parting line for the core and cavity.

Draft analysis:

Using the feature draft analysis,the given class A surface is draft analysed and from 2 degree to 2.2 degree draft analysis is good on class A surface.For 3 degree one of the wall is negatively drafted.

Tooling axis:

• A centre point is formed as reference point on base surface of the switch bezel.
• From the reference point,axis system is formed.
• Tooling axis along XZ plane:
  • intersecting the surface along XZ plane and a line along inclined surface is created.
  • From the line a tooling axis line is created along XZ plane.
• Tooling axis along YZ plane:
  • intersecting the surface along XZ plane and a line along inclined surface is created.
  • From the line a tooling axis line is created along XZ plane.
• Tooling axis by bisection method:
  • From the tooling axis line XZ & YZ plane,an axis line is created by bisecting the two tooling axis line.
