Week 10 - Challenge 2- Attachment Feature Creation (Dog House)
Door trim & Dog house Design
Aim:
To design the Door trim plastic component by using A surface and create the dog house by using design rules and the do the draft analysis on Door trim.
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 with design rules.
· Draft analysis of Door trim.
Introduction:
A Door trim is a part of an automotive door. 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. Doghouse is an engineering element used in the creation of plastic trim. Dog kennels are a supporting element.
Parameters:
Thickness of component -- 2.5mm
Draft angle of component – 3o
Draft angle of dog house - 0.5o - 1.5o
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.
