Week 8 - Challenge 4 - Bumper

1. To Create Bumper Using given Class A surafce, Tooling Axis Created in the direction Y,From which point the all faces of given Class A surface visible that point used to create tooling Axis using point direction method. In that direction only Core and cavity opens.

Class A surface

2. Draft Analysis made on Given Class A surafce using tooling Axis as draft angle. in that Class A surface was fully green it shows us all surfaces are 0 to 3 degree

Draft Analysis on Class A surface

3. After draft analysis Class B surface are created by offsetting the given class A surface to 3mm. In that offset some of the fillets are missing. To cover that Extract and Extrapolation method is used on where ever fillets are missed and new fillet given.

Class B Surface

4. To create class C surface, boundary of class A surface divided into severel cells and each of the boundaries were sweeped seperately and joined in some of the corners are not joined properly in that places sweep surfaces are removed and multi section has been used.

5. Finally Class A,B,C Surfaces are Joined together. But in joint of class A and Class C there is a gap in some areas. to receover that boundary of class A surface extrapolated to 0.05 mm, later it was trime with class C surface. After thet Class A,B&C surfaces are joined together.

6. On Final output draft analysis made. As considering tooling Axis as draft angle in that the result was front side full of green(0 to 3 degree) and inner surface fully red( above 3 degree).

7. Bumper that created in Surafce workbench was conerts to Close surface in part workbench.
