Week 9 - Challenge 3 - Bumper

 BUMPER CHALLENGE 

Object:- Create a tooling axis in a proper way for finding a better draft analysis from the given class A surface. Create a draft analysis of the class A surface and create the class B and class C surface from the class A surface. And finally, create the draft analysis of the finished body.

Consider the thickness of the component 3 mm.

Class A Surface:-

Given Class A Surface 

 

Checked the given Class A Surface element by a joint command 

Checked the boundary continuity using boundary commend 

Tooling Axis:- 

Here I have created a tooling axis. I extract a base surface and create a midpoint on it. And then I create a line through this point perpendicular to the base surface. And then I performed a draft analysis and I saw everything is ok. Then finally it is my tooling axis.

Draft Analysis of Class A Surface In CATIA:-

It provides colour-based identification. With the help of this, we can easily find which surface is clear and which is stuck by colour changes. Here I give the draft angle 3 degrees. The result in colour is based that the surface which is green. And where the colour is blue mean draft angle is 3 degrees to 0 degrees if this surface area is low then you can go. If you find a red colour zone then it means the draft angle is less than 0 degrees. Then you will have to create a tooling axis in another way if possible, otherwise, you can say your design engineer to correct for design.

Class B Surface:- 

Here I created a Class B Surface of 3mm from a Class A Surface.

 

Class B Surface with Class A Surface 

 

Class C Surface:- 

Here I created a Class C Surface using Tooling Axis.

Joining Class A with Class C Surface

Final Output

Give Class A Surface with Class B and Class C Surface 

Checking

Boundry commend whether it is closed or not 

Closed Surface 

Created the surface using Colsed body
