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

Aim:

To perfrom Draft analysis on a Fan Cover.

Theory:

Draft Analysis is performed to check the manufacturability of the product.In Draft Analysis, the Class C surface i.e.side walls are checked for draft. A minimum if 3 degrees draft is expected on the component to make it manufacturable without any damage to the product. The tooling axis of the product depends on the Draft analysis. Most of the component is deemed to clear in the Tooling axis,if any part in case can be cleared using Side core.

Procedure:

• Creating Tooling Axis using Bisecting method:

Tooling Axis is created using the Intersection method. At first the clearnace of the cavity is checked manually in all the possible direction. It is concluded that the z axis is the most feasable direction for tooling axis. So the X and Y axis are projected on the part using the "Intersection" command.

X axis tooling clearing is checked by making a bisecting line from two lines drawn in the z direction.The bisecting line clears the X axis.

Y axis tooling clearing is checked by making a bisecting line from two lines drawn in the z direction.The bisecting line clears the Y axis.

A final Tooling Axis is made by bisecting the X and Y direction clearing axes.This line gives the direction of moving of Cavity Die.

• Draft Analysis:

Draft Analysis is performed using the Draft analysis command. The Universal compass is fixed on the Tooling axis and the part is selected. The values of Draft are fed to get different color codes and a thorough inspection is done all over the part.

Observation:

The areas in Green colour will clear the Tooling axis with the required draft,making the part manufacturable.

Conclusion:

The Draft Analysis of a Fan Cover is succesfully performed and the Tooling Axis is made.
