Week 8 - Challenge 2 - Switch Bezel Design
Design of switch bezel,
Draft analysis,
Draft analysis, which is used to find out the proper tooling axis of a plastic component. it is a technique used to analyze whether our part model created in CAD is manufacturable based on the draft condition applied.
Draft,
Draft is an angle provided to the plastic part, which is used to ejects or removes the material from the mold easily without any damages. Draft is a taper applied to the faces of the part that prevent them from being parallel to the motion of the mold opening.

Steps for draft analysis using bisecting method,
- Refer the views of the given class A surface in X,Y,Z directions. finding out the direction where most of the surface are visible.
- Here, i have taken the X & Y direction, to find out the main tooling axis.
- An axis system fixed in the reference point for intersections purpose.
- Then using the Y axis, i have got the surface intersection.
- Based on the intersection two parallel lines has taken for Tooling clearing in Y direction.
- Above mentioned 2 steps were used for Tooling clearing in x direction, in x direction there is no opposite or parallel surface. hence one dummy line has drawn which is parallel to the x direction intersection then the maximum draft angle 3 deg considered to align the line.
- Bisecting method, using the tooling clearing in X & Y direction line, a line has drawn using bisecting line method. this line is refered as main tooling axis.
- In the main tooling axis the draft analysis compass has fixed and used the running point i have measure some points. at the end i have found out the draft angle as 2.9 deg for closure cat part.
- And i have changed the green side in top using the flip option, have changed the colors in color scale.
- At the end of class A surface draft analysis i have got complete green surface ( cavity side ).
- At the end of solid part draft analysis i have got cavity side as green in color, core side as red in color.
