Week 8 - Challenge 3 - Coin Holder Design

1. A detailed report should be done explaining the draft analysis at the Class A surface.

Draft analysis on Class A surface of Coin holder-
Step 1- Open draft analysis and move the compass to coincide with the Tooling axis

Step 2- Lock the compass and check the radius/angles using the running analysis option-\

Step 3- Set the color code for the draft angle i.e green for above 3 degrees, Blue for 0-3 degrees, and red for angle value lesser than 0.

Step 4- Click on the surface using light effect, if the color goes green throughout means your draft analysis is good and ready for manufacture-

Now Creating Class B and Class C surface for Coin Holder-

2-An explanation should be given on the way of creating the tooling axis, particularly the Bisecting method.

ANS- Tooling Axis-

Now creating the tooling axis by using an intersection and a dummy axis-
1. open the file which contains the Class A surface, after creating a geometrical set "Tooling Axis" then select the most appropriate position, and in this select a base of the tub/pocket.

2. Then create a point at the surface extracted then draw a dummy line on the z-axis.

3. After that create a plane on the point created with reference to the Z direction.

4. Then select the intersect tool that gives the intersection on the Class A surface.

5. In this it can be clearly seen that a wall of coin holder is parallel to the Z axis as shown below screenshot.

6. the Last step creates a line normal to the plane or surface which can be used as a Tooling axis.
