DESIGN FEA

AIM:

To Create the Door Handle Component from the given Class-A surface.
To Create the tooling axis for the given Class-A Surface meeting the requirements of the draft angle.
To Attach B side Features in the component.
To perform the Draft analysis on the model.

TOOLS USED:

Boundary
Join
Multiple extract
Bisecting line
Trim
Surface offset
Draft analysis
Intersect
Surface sweep
Close body surface

DESCRIPTION:

CLASS A SURFACE : them input which given is called class a surface

The Tooling Direction is basically the direction that the mold pulls a part. The mold is built in two separate pieces, basically. You have a Cavity side and you have the Core side. The Core pulls apart from the Cavity and that's the Dye line or the Tooling Direction.

Open the given CAT part file.
Check for gaps between surfaces for that click on join and then preview.
If theres any gap between the surfaces join them with a maximum tolerance of 0.003 mm.

TOOLING AXIS :

i created tooling axis using normal to the surface method i
extracted the srface
inserted a point at exactly centre of that perticular surface then i draw a line which is normal to the surface

The tooling axis is created for the component by bisecting two axis from x and y planes.

DRAFT ANALYSIS OF CLASSS A SURFACE

The Draft Analysis command enables you to detect if the part you drafted will be easily removed. This type of analysis is performed based on color ranges identifying zones on the analyzed element where the deviation from the draft direction at any point, corresponds to specified values.

Before going to drat analysis go to customized view parameter >under mesh >check material and then click ok.
Now for draft analyses go to insert » analysis » feature draft analysis.
Use the compasss to define the draft direction.
In the colour scale change the draft angle to 3 degree.
The component changes to green in indication of passing draft angle.
Use running point to check the angle on the component.

The draft analysis is complete.

4. CREATING CLASS B SURFACE

I offested the class a surface
then the surface got failed at some fillet areas
by using multi section surface command i re created the fillet

the bellow picture shows that how the surface failed at the fillet areas

the bellow surface shows using multi section surface command i re created the fillet

5. CREATING CLASS C SURFACE

Extract the boundary from the class A surface using boundary command.
Using disassemble tool to divide the boundary as the boundary contains domains.
Use sweep command > choose profile type line > subtype as with draft direction > choose guide curve and draft direction > draft angle as 3 degree > preview.
