Week 11 - Project - A pillar Design with Master Section

A Pillar & Dog house Design

Aim:

To design the A pillar plastic component by using A surface and create the dog house by using master section and the do the draft analysis on A pillar.

Objectives:

· Create a tooling axis by using intersection lines.

· Creation of class B surface by using extract and offset.

· Creation of class C surface by creating sweep from A surface and extrapolate from B surface.

· Creating a solid part by using of close surface.

· Creation of Dog house by the given master section.

· Draft analysis of A pillar and dog house.

Introduction:

A A pillar is one of the part of an automotive parts. Every plastic components have a A,B,C surface. A surface is the basic surface. By using the A surface only, we can design the plastic components. B,C surface creating only by using of A surface. Tooling axis is very important to design a component. For draft tooling axis is essential. For C surface creation from B surface the sweep created by use of tooling axis.

Parameters:

Thickness of component - 2.5mm

Draft angle of component – 3^o

Draft angle of Dog house – 0.5deg

Class A surface:

This picture shows the class A surface. First, we need to check the boundary. If it is not okay, then A surface needs to be modified.

Tooling Axis:

Tooling axis needs to be created by using of A surface by using intersection lines by bisecting method.

Draft Analysis of Class A surface:

Draft angle – 3deg.

Class B surface:

This picture shows a class B surface. This was created by extract and offset the A surface and splitting the extract surface. Finally extrapolate the component for making closed sheet to make solid.

Class C surface:

This picture shows the class C surface. This was created by use of creating sweep from A surface and trim with the B surface.
