Week 8 - Challenge 3 - Coin Holder Design

Aim-

Create a Coin Holder Plastic component through the given Class-A surface. To begin with, the tooling axis for the given Class-A Surface should be created meeting the requirements of the draft angle and at the end perform the Draft analysis on the model.

Make the thickness of the component to be 2.5 mm

INTRODUCTION:

CLASS-A SURFACE:

A surface made by the designer is given as an input to the plastic modeler to work on. It is an aesthetic surface and the outermost surface.

CLASS-B SURFACE:

A surface below a certain thickness from the class-A surface is a class-B surface. This is the surface that contains engineering aspects of a model.

CLASS C SURFACE:

The surface that joins class-A and class-B surfaces is a class-C surface.

TOOLING AXIS-

The tooling axis of the product tells us the direction of movement where the part is being produced effectively.

Draft Analysis FOR CLASS A:

1. Draft analysis is done after determining the tooling axis, draft analysis is used to check whether the minimum draft (3 degrees) is maintained or not.
2. Compass is used to define the draft direction.
3. As the class-A surface is made by another designer only he is authorized to make changes, so we look over this to complete the coin holder for practice.
4. Now we will go to insert< analysis< draft analysis and follow the usual procedure to do the analysis.
5. Align the compass and click on the surface and as expected the model is mostly in red color i.e. negative draft with respect to the axis.
6. To correct it as best as we can we moved the compass a bit till we got most of the surfaces in green and locked that position. After hitting OK, we change the direction of the line from the z-axis to the compass direction. The axis will align itself accordingly.
