Week 8 - Challenge 3 - Switch Bezel Design
AIM:Creating the Switch Bezel Plastic component through the given Class-A surface and performing Draft Analysis on bothsolid component and Class A-Surface.
DESCRIPTION:
Draft Analysis:
Draft is the angle in which the part is tapered for easy ejection from core and cavity block.
Draft analysis is a technique used to analyze whether the drafted CAD model is manufacturable with the given draft conditions.Tooling axis (the direction in which the mold is ejected) is provided, so that there should be a smooth ejection of thesurface/part from Core-Cavity block.
A.Steps involved in creating TOOLING AXIS:
1. Extract a surface and create a point on that surface.
2. Create axis system on the point.
3. Create sketch on YZ-plane and using bisection of lines we get Tooling axis clearing Y-Direction.
4. Create sketch on XZ-plane and draw a line at an angle of
5 degreewith the line created on the 3D intersection projection, thisis our Tooling axis clearing Y-Direction.5. Now, create a bisecting line using the Clearing axis and a point.
This bisecting line will be our Tooling axis for Switch Bezel.
6. Publish Tooling axis and Class A surface of Switch Bezel for easy selection.

B. Steps involved in creation of Class B-SURFACE:
1. Extract the simple surfaces (which don’t have fillet) and then untrim the extracted surfaces.
2. Extrapolate and trim the surface as per requirement.
3. Offset the trimmed part to a distance of 2.5mm.
4. Now perform the fillets at the edges.
The fillet radius is chosen in such a way that there should be equal thickness at the curved surface.
C. Steps involved in creation of C-SURFACE.
1. Extract the OUTER boundary of the class A-surface and apply smooth curve separately to the boundaries.
2. Sweep the boundaries along the TOOLING AXIS separately.
