Week 8 - Challenge 4 - Bumper

Tooling Direction :-

Tooling axis is the direction in which mold or core and cavity opens. The ejection of the part from mold depends on the draft. A zero draft can result in difficult or no ejection due to shrinkage. It is recommended to add a minimum of 0.5 to 1 degree of the draft for non-textured surface & 3 to 5 degree of draft for textured surfaces.

Procedure to create the tooling axis using bisecting method :-

following Class A surface is provided to design the bumper plastic component.

Point is created on the plane Surface

The tooling direction

Draft analysis :-

Draft 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. Minimum draft angle is considered as 3 degree.

B-Surface :-

Class B-Surface is extracted from the A-surface and it is offseted at 3 mm in Upward direction.

C-Surface :-

C-Surface connects the class A-Surface and B-Surface. It is created using Blends command. Boundary of the class a surface to create class c surface using blend and joined with Class A Created Surface C.
