Week 8 - Challenge 3 - Switch Bezel Design

Ex-03:

Aim:

• To create a Switch Bezel using class A,B and C Surfaces.

Tools Used:

• Line
• Point
• Bisecting
• Intersection
• Draft Analysis
• Extract
• Sweep
• Trim
• Extrapolate
• Edge fillets

Draft Analysis:

• Drafted parts can be easily removed from the die, for a plastic surfaces the draft angle should be @ 3deg and for a sheetmetal part the draft angle should be @ 7deg.
• This type of analysis is performed based on color ranges on the part to identifying zones.

Tooling Axis:

• This axis represent the tooling direction,This tooling axis can be defined by edges on the class A surface and bisecting these two lines from the class A surface gives the tooling axis.
• The below fig represent the tooling axis which is indicated in blue color.

        

Procedure:

• Create a point and the intersection line from the class A surface.

        

• Create a centre line from the class A surface.

        

• Create another line from the right side view and intersect the line.

        

• Create a bisect line from these two lines.

        

        

• Create an extract from the class A surface,untrim,extrapolate and offset it to 2.5mm

        

        

        

• Trim the excess portion and add edge fillet to it.

        

        

• Create Class C surface by creating boundry on the class A surface and sweep it.

        

• Join the class A and C surface together and trim that surface with Class B surface and consider that all the boundries are closed.

        

• Make the surface into solid body by using close surface tool.

        

• Create an draft analysis and ensure the surface is in green color i.e the surfaces are satisfying the draft angles.
