Week 8 - Challenge 4 - Bumper
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 design Its have more accuracy than other.
Class A Surface :-
In automotive design application Class A Surfaces are created on all visible exterior surfaces and all visible surfaces of see-touch & feel parts in interior This can also include beauty covers in the engine compartment, mud flaps, trunk pannels andarpeting.

Tooling Axis :-
Tooling axis or tooling direction is main consideration for plastic part and mold parts because it defines movement of mold part and possibility of plastic part to come-out from mold part (Core and Cavity). In Molding machine arrangement is given to open the mold along a direction which is known as Tooling Direction. The mold is built from two separate halves (Core and Cavity) and tooling direction basically define the direction of mold pulls apart. Tooling direction is known as primary direction.
- Here I have created a tooling axis. First of all I extract a base surface and create a mid pont on it. And then I create a line through this point with perpendicular to base surface. And then I performed draft analysis ans I saw every thing is ok. Then finally it is my tooling axis.

Draft Analysis :-
The Draft Analysis allows the user to easily analyze a part for proper draft angle. A Draft Angle describes the amount of taper for molded or cast parts perpendicular to the parting line. Draft Analysis is applicable for 3D part models. To create a draft analysis for any 3D part file, the user needs to select part/surface select the pull direction. You can change the pull direction.

Class B Surface :- The surface which is back side of Class A surface is called Class B Surface. Mostly it not visible. It is created with the help of Class A surface with some distances like 2mm, 3mm etc.

CLASS C SURACE:

ADDING OF CLASS A AND CLASS C SURFACE:

FINAL BUMPER:


Conclusion :- In this project we can learn how to create tooling axis and creating of class b& class c surfaces and finally we completed bumper design
