Week 8 - Challenge 6 - Core & Cavity Design

Design Methodology with images:

Procedure for Parting Surface:

• Extract the Class A surface boundary lines with boundary option.
• Extrapolate the Class A surface by 15mm.
• Trim the extrapolated surface with Class C & B surfaces respectively.

Procedure for design Core:

• Open the new sketch in XY plane.
• Create a rectangle and constraints it.
• Extrude the sketch on both sides.
• Trim the parting surface with the above surface of the rectangle.
• Fill the open surface with the Fill option.
• Join the filled surface with the trimmed surface.

Procedure for design Cavity:

• Trim the extrude surface with b surface.
• Fill the open surface with the Fill option.
• Join the filled surface with the trimmed surface.
• Now open the Part body.
• Create two bodies separately and create closed surfaces.
• Intersect with the perpendicular plane and unhide the tooling axis.
• Translate the bodies in required directions.

Procedure for Draft Analysis

Draft Analysis:

• Go to the Insert menu and select the Analysis option.
• Select Feature Draft Analysis.
• Select the Material option and select the surface.
• Drag the compass and place on tooling axis.
• Make sure that the top surface is in green colour as draft angle should not exceed 3deg.
• Click on Okay after confirm the model.
