Door Arm Rest Week 8 Challenge

Objective:- Objective of this challenge is to Creation of Door Arm rest and add thickness to it using CATIA Software. And also create Class A surface, Class B surface and Class C surface and Solid Pattern for manufacturing.

Tooling Axis:- The direction in which mold opens or Core and cavity get separated, is called the Tooling axis.

Class A Surface:- It is a surface that we get as input from Alias software.

Class B Surface:- It is a surface that we create at offset thickness from Class A surface.

Class C Surface:- It is a surface that we create to join Surface A and Surface B.

Phase 1:- In phase 1 we import Class A surface in Catia. That Class A surface may be in the different part surfaces, so we join them using JOIN Command in CATIA. For confirmation of joining we use BOUNDARY command, If boundary shows no error then we go for phase 2.

Phase 2:- In Phase 2 we create Tooling axis of the product then we do draft analysis of it.

We create a dummy tooling axis by visualizing the product. We choose dummy tooling axis such that product's manufacturing will be easy. In our Base cover along Z axis will be our dummy tooling axis.

Side Core Tooling Axis

Phase-3:- Now we go for the final phase in which we make the Final Pattern.

Then we create Class B surface at an offset distance of 2.5 mm that is the thickness of pattern.

We use Extract, Untrim, Extrapolate, Trim, Fillet, Offset and Join command.

After that we Create Class C surface which joins Class A and Class B Surface.

Here we use Boundary and Swept and Join Command.

Then We create final pattern using The close surface command in part design.

Then we do draft analysis of pattern.

PUBLICATION:- We do publication using publication command available in Tools to easily access the part.

Here are the images of final pattern.
