Week 8 - Challenge 4 - Bumper

DESIGN AND DRAFT ANALYSIS OF BUMPER

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

Consider the thickness of the component 3 mm.

Introduction :- This project is done on CATIA software. This software is different from other. It is easy to designing for surface modelling. Its have more accuracy than other.

Class A Surface :-

In automotive design application Class A Surfaces are created on all visible exterior surfaces (ex; body panels, bumper, grill, lights etc.) and all visible surfaces of see-touch & feel parts in interior (ex: Dashboard, seats, door pads etc.). This can also include beauty covers in the engine compartment, mud flaps, trunk panels and carpeting. This surface has 0 mm thickness.

Creation of Tolling axis:

To create the tooling axis first we have to check the best suitable direction for tooling by using the compass. the x direction is suitable for creating the tolling axis because in the x direction most of the surfaces are clearing while performing draft analysis. Generally tooling axis is created using bisecting line method but here A line normal to the surface is created in the x direction and considered the tooling axis.

Draft analysis of Class- A

After creating a tooling axis we do the draft analysis. Before drafting we have to make sure that in the view mode it is selected for the materials.

After selecting the feature draft analysis tool we drag the compass from its position to the tool axis. Then lock the compass. After that select anywhere on the component and it will give you the result.

We change the minimum draft for the component to 3°.

We can use the running point option to check the angle of the component.
