Week 8 - Challenge 3 - Coin Holder Design

Report:

Objective:

Is to design the Plastic model to pass the feasibility check to avoid the manufacturing error.

Tooling Axis:

Tooling axis is create to show the tooling direction which show the movement of the Mold and cavity & to exit the part without damaging the surface.  

Created the tooling axis on normal to surface.

Draft Analysis:

The Draft Analysis allows the user to easily analyze a part for proper draft angle. A Draft Angle say the amount of taper for molded or cast parts perpendicular to the parting line.

At first draft anaylsis is performed to the given Class A Surface to check the draft angle.

Step 1:

Click the Draft Analysis in the Analysis tool bar.

Step 2:

Placed the Compass in the tooling axis and Activated the compass in the draft analysis box and reposition the compass.

Selected the Class A Surface.

Step 3:

After selecting the surface it changes the color into green. It show that the Class A surface has perfect draft angle. If it show the Blue color try to create the tooling axis in normal to surface.

This how it will show the color changes.

Step 4:

After draft anaylsis, Class B surface is created for given offset vaule 2.5mm

Step 5:

Class C Surface:

Class C surface is created by doing the Sweep command from the class A surface along the draft direction option. By giving the draft angle as 3 degree outward from the A surface. By giving the draft angle as 3 degree so the parting line will not occur in the Class A surface. 

 

Extrapolated the C Surface and Trimed. Then the Class C and Class A surface is joined using the trim command. 

  

Joined A&C Surface is trimmed with the Class B surface. It is will be the Final Trim.
