Week 8 - Challenge 6 - Core & Cavity Design

Aim : Create the Core and cavity blocks for the switch bezel designed in the earlier challenge.

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.

For design the core cavity first take draft analysis of solide component which is make from class A surface and B section and combine with C surface .

Core Design:

nitially, I have taken the boundary of the class A surface to extrapolate it. After extrapolating the class A surface I trimmed extrapolated class A surface and class C surface (join of class A and sweeped surface), after I trimmed the class B surface with Trim.5 to create the 'Parting surface'. Now I draw a rectangle, which does not exceed the boundary of the parting surface.

Parting surface trim:

Rectangular extrude:

Trim for Core block:

Core block:
Closed surface:

Cavity Design:

To create the cavity block, I trimmed the rectangular extrude with a class B surface to remove the surface which is the upper side of it. After that, I filler the surface which is opened, to make a closed surface by joining both trim and filled surface. Now create a solid body from the closed surface by using the closed surface. The obtained part body from the closed surface is our CAVITY block.

Trin for Cavity block:

.

PARTING LINE:

To create a parting line I take an intersection of class b surface and class c surface (class c surface- join of class A and sweep).
