Week 8 - Challenge 3 - Switch Bezel Design

Creation of Main Tooling Axis:

On visual inspection of the class A surface the faces highlighted in blue are indentified as faces that may cause problem in the ejection of the component from the mold. Hence the Z- axis is chosen as the direction for the toolling axis.

1. Extract the bottom face. Make a point on this surface with offset zero so as to center it and consider this point as the origin.
2. Hence a sketch is made in the YZ plane and the intersection of the class A surface is taken, now a bisecting line of these 2 faces is taken and plotted.
3. Another sketch is made on the ZX plane and and the intersection of the class A is taken again, since there aren't 2 faces to take a bisection line just draw a line with the origin and give an angle constrain of aroud 5 degrees for a clear draft analysis.
4. Take both thes lines and make a bisection line with the origin to get the tooling axis.

Draft analysis of class A surface:

Take a draft analysis of the class A surface to ensure that the tooling axis selected is appropriate.

Creation of B surface:

1. Select all the faces of the component and extract and untrim them.
2. Extrapolate all of these surfaces to ensure that they inersect.
3. Take an offset of these faces below the class A surface according to the thickness of the component needed.
4. Hide the initial faces and trim the offset faces.
5. Give the necessary fillets keeping in mind the rules for filleting.

Creation of C surface:

1. Multi-Extract the boundry of the class A surface in 2 parts i.e. front and back
2. Select the sweep command with draft direction and generate the 2 surfaces.
3. Extrapolate and tirm the surfaces to form a single surface.

Creation of closed body:

1. Select the A,B,C surfaces and trim them appropriately.
2. Check for any open boundries with the boundry or join command.

Creation of solid body:

Use the closed body command in the part workbench to create a solid body.
