Week 8 - Challenge 5 - Core & Cavity Design

Objective:

To create a Core and Cavity of Switch Bezel.

Procedure:

Creation of Parting Surface:

• To create parting surface select boundary command on Class A surface.
• It gives outer line of Class A.
• Extrapol the Class A Surface.
• Trim the outer edges by selecting Extrapol.19 and Trim.11 i.e the Class C Surface.
• Trim the unwanted region by selecting Class B surface and Trim.14.
• Draw a Rectangle with Sketch with an Axis sytem on the base along

Creation of Core Design:

• To Create Core Degin Extrude the Rectangle ie. Sketch.3 along the Tooling Axis for 150mm.
• Use boundary on the Top edges.
• To close the top use Fill command.
• Join the Trim.16 and Fill.1
• Convert the joined surface to a soild body by close surface from Part Design.

Creation of Cavity Design:

• To create the cavity design extrude the rectangualr surface.
• Trim the Extrude.2 along with CLASS B Surface.
• Use Boundary command to select the bottom edges.
• Use Fill command to close the bottom side.
• Join Extrude and Fill to create a closed surface.
• Convert the joined surface to a soild body by close surface from Part Design.

Creation Of Parting Line:

• To create Parting Line Multiple Extract the Class A edges.
• Use Sihouette command using MUTIPLE Extract and Tooling AXIS.
