Week 8 - Challenge 2 - Switch Bezel Design

SWITCH BEZEL DESIGN

CLASS A SURFACE

It is the surface which is given to the plastic designer as input.it is the outer most and aesthetic surface.

CLASS B SURFACE

A surface that is at a distance of thickness from class A surface is class B surface.all engineering features are contained in B surface.

CLASS C SURFACE

A surface that joints class A and class B is called C surface.

TOOLING AXIS

• First look at the part in all views and check which is the most appropriate direction for the tool axis.
• Then make a bisecting line between 2 inclined surfaces in the YZ plane.

• Then project the inclined surface in the XZ plane.and draw a sample line parallel to that surface and make it 3 degree from the projected line by constraining it.

• Then draw a bisecting line between these 2 lines which is the final tooling axis.

DRAFT ANALYSIS

• Draft analysis is done to check whether the part designed is manufacturable or not.
• Minimum draft angle considered is 3*.
• For analysis goto insert>analysis>feature draft analysis.then place the compass on the tooling axis and click on the part.
