Week 8 - Challenge 2 - Switch Bezel Design

Report on draft analysis and tooling axis creation

Draft is provided to a plastic component so as to avoid the difficulty in retracting the cavity mould after injecting the plastic into the cavity.

The minimum draft to any plastic component should be 3 mm.hence the Class A surface of Base bracket is analysed for a draft.

The given class A surface consists of three walls at an angle to the base,and the angle must be >3° to the vertical.

Tooling axis creation

1.Insert a point on the base of the switch bezel

2.Insert an axis system on the point and take the cross-section of the two walls

3.Draw a line Bisecting the two lines.

4.consider the third surface and draw a line coincident to the wall.

5.draw a bisecting line to the previous line and the other line bisecting the lines of the two walls.this line becomes the Tooling axis of the surface.

6.now moving on to feature a draft analysis place the compass on the axis and lock it.

.selecting the mode to full analysis and adjusting the colour variants to different degrees we can get the draft angle analysis of the surface in different colour mode.
<0°-Blue,0°-3°Red,>3°-green.

after performing the feature draft analysis the surface was found to be meeting the requirements of the draft.
