Week 8 - Challenge 6 - Core & Cavity Design

Objective: The main objective of this challenge is to design a Core and Cavity for a Switch Bezel' in CATIA V5 with the help of a surface workbench.

Before we design the core and cavity, we should perform a draft analysis on the solid part body of the switch bezel.

Tooling axis :

• To create the tooling axis, we need the proper orientation or view that gives the correct features and draft available in the component.
• So here the component view from the Z direction gives the proper view for the tool to see the features present in the geometry.
• To create the tooling axis from the Z direction we need the tooling axis from the other X direction since it gives the draft available at the slanted part.
• The tooling axis created from the X direction by following steps
  1. The base surface is extracted.
  2. Then the center point is created using the point > on the surface at 0
  3. At the point created the axis system is created
  4. After that switching the view of the model to the X direction and creating the tooling axis.

  Using the intersect in ZY plane to get the boundary lines.

  Then the lines are created along the slant surfaces.

  Then these two lines are bisected to get the tooling axis for the X or the final

  1. Next, switching in the Y direction and intersecting the switch bezel part in ZX direction to get the intersecting lines.
  2. Using the axis center point, a line is drawn in sketch mode and it is constrained at the angle of 4 degrees. (this angle value is an arbitrary value and can be changed to get the final tooling axis that provides a positive draft )
  3. At last, both the lines are bisected to get the final tooling axis.
