Week 8 - Challenge 6 - Core & Cavity Design

AIM : To Create the Core and cavity blocks for the switch bezel design .

A detailed report should be done explaining the draft analysis and the tooling axis creation :

1)DRAFT ANALYSIS :

Follow steps : Go to insert> analysis> feature draft analysis
Place the compass on the Tooling axis that is created using bisecting method.
Click on the surface and see that the surface is within the permissible limit of the draft values.
The surface should be green and nominal draft value should be 3deg .
Thus the draft analysis on the class-A surface is successfully performed.

2) CREATION OF TOOLING AXIS DIRECTION USING BISECTING METHOD :

First ,the base surface of the class A surface was extracted and a point at the centre is created and then an axis system was inserted to the point .
Then, using project intersection along yz plane is created first and the two inclined lines were drawn inside the positioned sketch.
Then bisecting lines with the two inclined lines were drawn.
Now the same procedure is repeated along the xz plane next but on one side we don’t have inclined lines so the centre point is used to extrude a line along the z-direction and gave a measurement of 3 degrees .
With these two lines from sketches 1 and 2, the bisecting line is created . This will be the correct tooling axis for the component .
