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

Aim

To create the tooling axis for the given class A surface and perform draft analysis for the tooling axis.

Procedure

The class A surface was checked for open surfaces using Join > check connectivity and no issues with connectivity were found. The screenshot is given below.

The tooling axis was created using bisecting method. For this, intersection of the class A surface with X plane was created.

Lines were created through the intersection of faces with the X plane to determine the tooling direction in x plane.

The tooling direction was created using line > line type was set as bisecting > intersection lines were selected as input for Line 1 and Line 2 > centre of the hole was selected as input for point > OK.

Similarly for y plane the intersection was created and tooling direction in y was determined.

Results

The tooling axis is determined by bisecting the tooling directions in x and y directions. The image of the tooling direction is given below.

The draft analysis performed on the class A surface for 3° is shown below. All the faces were clearing for 3° draft.

However for 11° draft some faces were failing.

The image of the tree is given below.

Conclusions

Therefore we can conclude that this component is manufacturable with minimum degree of draft required.
