Week 8 - Challenge 4 - Bumper

TOOLING AXIS CREATION AND DRAFT ANALYSIS FOR THE GIVEN CLASS A SURFACE (BUMPER)

Objective: Creating the Bumper plastic surface through the given Class-A surface. The tooling axis for the given Class-A Surface to be created meeting the requirements of the draft angle and at the end performing the Draft analysis on the model.

Class A surface of the Bumper is given for designing the plastic component

Class A surface

It describes the final production surface data for the part

From the given Class A surface a tooling direction is created on the feasible surface. Here i have created the tooling direction at the center to the fog light area. After defining the main tooling axis draft analysis for a postive draft of 3 deg

he green colour on the surface represnets that there is no negative draft

Class B surface

To create the class B surface from Class A we have to offset the class A surface to a thickness of 3 mm

After the offset we have found that some gaps are formed on the surface by using sweep and multi section features we can fill th gaps formed and B surface is created

Class C surface

Extract the outer flange surface from class a and extract the border. use the sweep feature to the border at 90 deg to the surface and join with class A surface.

Class C surface is created

Trim the class B surface with class C surface to get the closed surface, using closed surface feature convert into solid body.

Draft analysis is done for the final closed body
