Week 8 - Challenge 2 - Switch Bezel Design
Aim:
To create a switch bezel platic component using with the reference of class A surface and perform the draft analysis and check the part is proper manufacturing component.
Draft analysis:
draft analysis is a techinque is used to analyze whether our part model created in catia V5 is manufacturable based on the draft condtion applied. Here the part should get easly removed from the mold.
No parts can be ejected from the tool if it is having straight 90 degrees profile from its base surface. Asmall draft angle provided to each an every area of the component inorder to get easly removal of component from the tool.
Here we are providing or assuming a direction in which component should eject in order to get easly removal of components from the tool. In other words let us know whwther the model is having a draft angle and how much is the draft angle from the tool direction.
Procedure for Draft analysis:
- Fisrt check the continuety of given Class A surface.
- Check three directions (X, Y & Z) and dicide which is the best possible dirction to produce a mold.
- At Z axis direction in the faces are either positive or negative so the Z axis we tacken as dummy tooling axis
Tooling axis creation:
Direction which mold opens or cavity opens.
create a point at center of base sutface and create axis sysytem on apoint create an intercection line along ZX plane on class A surface.
Then create a line along YZ plane which line is inclined to the intersection of class A surface
then use the bisection of both lines along with the center point
Extend the line that you want to create tooling axis for the model the do the draft analysis using the line axis.
Draft analysing method:
insert-analysis -feature draft analysis. Select compass icon in draft analysis dialogue box and drag the compass and place it into the tooling axisselect to draft direction option switch to quick analysis mode see whether surface are passed draft angle or not.

Conclusion:
Draft analysis is done in the given model and get positive draft
