Week 9 - Challenge 1 - Base Bracket Design

BASE BRACKET DESIGN

OBJECTIVE: To design the base bracket by working in the given class A surface by creating,

• Tooling axis
• Performing draft analysis
• Creating class B and C surfaces.

CREATING A TOOLING AXIS

• First i anaysed the part and then created a dummy tooing axis along the z axis through the reference point created.
• The reference point was created in the center of a circle in the flat face of the component.
• I intersect the boundary of the component in the yz plane and created 2 lines in the sloped faces.
• created bisecting line to get the final tooling axis.
• Published the tooling axis.

DRAFT ANALYSIS

• First i put the part under material mode.
• Insert> Analysis> Feature draft analysis.
• Two windows appeard and one of it shows the colour scale of the draft angle.
• Then i drag the compass and placed it along the tooling axis on it and locked it.
• Clicked on the component so that it turns green and analysed the draft angle in different faces of the component.
• Minimum draft angle is considered as 3 degree.

CREATING CLASS B SURFACE

• For creating the class B surface i visualized the component as 4 parts; Rib1,Rib2,Flat face and a Slopped face with hole.
• I performed the following oparations on these parts separately in an orderly manner.

1. Extracted the faces excluding fillets.
2. untrimmed it.
3. Extrapolated each face.
4. Trimmed each to shape
5. Offseted to given thickness of the component.
6. Trimmed all 4 parts together.
7. Finally fillets were given.

CREATING CLASS C SURFACE

• Class C surface is created using Sweep command.
• Boundary of the class A surface is swept along the tooling direction with 3 degree as angle.
• Then i joined class A and C.
• Trimmed that Join with the class B surface to get the final closed component.
• Then under the partbody used the close surface to make the component solid.
