Week 8 - Challenge 4 - Bumper
OBJECTIVE
Create the Bumper Plastic component through the given Class-A surface.
PROCEDURE
- Creation of Tooling Axis
- Creation of Class B surface
- Creation of Class C Surface
- Perform draft analysis
CREATION OF TOOLING AXIS
Tooling axis is the direction in which the mold and cavity opens and closes in the injection molding operation.
We have created a point on the corner of the part and created a line, that line is our Tooling axis.
DRAFT ANALYSIS OF CLASS A SURFACE
Draft analysis is done to know wheather the part will be easily manufacturable by the given draft angle or not. It will ensure that the part will not stuck in the core and cavity.
PROCEDURE TO PERFORM DRAFT ANALYSIS:-
- Right Click on Tab < Go to Analysis < Feature Draft analysis
- Put the View Mode in material option
- Align the compass with the tooling direction line
- The surface will turn into green colour it means the part is manufacturable with the given draft angle.
We have given minimum 3deg. draft and the green colour parts are easily removed from the mold.
CREATION OF CLASS B SURFACE
Class B surface is used for Engineering purpose. All the design parameter are done on the Class B surface. We have offsetted the Class A surface for 3mm to create CLASS B Surface. After offsetting, we have fixed some error surfaces of the part.
CREATION OF CLASS C SURFACE
Class C surface is used to join the Class A and Class B surface together. For this surface Customer feels do not need to meet a high cosmetic finish. By using sweep command in CATIA we have created the C surface.
SOLID SURFACE
We have first joined the CLASS C surface with CLASS A surface and then trimmed it with CLASS B surface, so it automatically joined together and formed a closed surface then we made it a solid surface.
