Week 8 - Challenge 1 - Draft Analysis on a Fan Cover

Draft Analysis of Fan cover model

Draft Angle: Draft is required to eject the parts from the mould properly. Draft is the angle in which the tapered is allowed to release. The minimum draft angle is ½ or 1 degree but 3 degrees is widely accepted.

Tooling Axis creation:

Initially the boundary is taken from the given model as shown in the fig.

And now create a point taking the center as reference after creating point we have to make intersect as shown in the direction below

The desired output is shown in the plane

After this create a dummy axis at the point.

Two lines are drawn on the surface of the model to obtain a tooling axis from bisecting method.

Now bisect the two lines and draw a line taking the point as reference the line drawn is X tooling axis.

For Y tooling axis again we have to intersect and draw two lines and bisect them to obtain Y tooling axis

Finally bisect the X and Y direction axis to get the final tooling axis.

Draft Analysis:

This makes the weather the model to be designed or not.Firstly the draft angle should be min of 3 degrees.This can be checked through colour variant if it shows green it is suitable.After this Analysis under running point is done to check the draft angle.
