Week 8 - Challenge 4 - Bumper
BUMBER 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
- The tooling direction is used to find the direction in which the part is ejected out of the mold.
- First look at the part in all views and check which is the most appropriate direction for the tool axis.
- For this surface we can see that in X direction is suitable for the tool axis since all parts are visible in x deirection.
- Then we check the angle between the problem making surface and x axis.

- Since it is greater than 3 degree tool axis in X direction is ok.

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.
