Week 8 - Challenge 1 - Base Bracket Design

AIM : To Create the Base Bracket Plastic component through the given Class-A surface

• Report should be done explaining the draft analysis and the tooling axis creation :

FOR DRAFT ANALYSIS :

1. Follow these steps : insert< analysis< feature draft analysis.
2. Drag the compass and place it on the tooling axis created
3. Now Click on the surface and see that the surface is within the permissible limit of the draft values.

4.The surface should be green and maintain the 3deg draft angle as shown

• 

FOR TOOLING AXIS ON BISECTING METHOD:

1. First ensure that the class-A surface is properly joined and has no discontinuity on it. To check we can use join command or boundary command .
2. Analyze the model manually or visually to see which direction is most suitable for creating tooling axis.
3. As in 3D view we can see 2 holes and a flat surface, we can directly take the tooling axis perpendicular to that. But to be sure,let us analaze from all the views. The below images of the front side and top views shows the areas that we have to keep in mind while choosing tooling axis.
4. As from X we cannot see one hole so we cannot take axis along this.
5. In Y we cannot see any holes so here too we cannot take tooling axis.
6. But in Z we can see 2 holes and flat surface so we can take tooling axis.

In X direction :

In Y direction :

4. Intersect the ZX plane of the axis system with the input and we can see that there is no surface that can create problem during tooling in this direction.

5. Intersect ZY plane and we are unsure of these two surfaces, so we make a line and bisect them both and this will be our tooling axis .
