Week 8 - Challenge 3 - Coin Holder Design
Draft angle: The degree of taper of the side wall of the mold or the angle of clearance designed to aid the removal of a part from a mold.
Most of the parts have a draft angle of min 3, but while designing we follow the general thumb rule of 1-degree draft per 1-inch depth.
Draft angle is provided along the TOOLING AXIS.
Tooling Axis: It is the direction in which the core and cavity of the mold move for the removal of the component inside it.
Creation of Tooling Axis:
- First, inspect the given CLASS A surface. Use the join feature to check whether the surface has a continuous boundary or not.
- Then check the direction in which the component can be easily molded without any complications.
- I have extracted the base surface and created the normal at the center of the surface.
- Then performed the Draft Analysis using the normal as TOOLING AXIS, and the component got cleared.
Draft Analysis Using Tooling Axis:
- After generating the Tooling Axis of the given CLASS A surface, insert the feature draft analysis from the analysis toolbox.
- Drag the axis system and try to align along the Tooling Axis.
- We observe the Draft analysis box that contains the mode, display, direction, and information of the tooling axis.
- Using the Draft analysis box complete draft analysis is performed and different draft angles are coded in different colors.
