Week 8 - Challenge 2 - Switch Bezel Design
Aim: To creat a solid model from the given class a, and create tooling axis, draft analysis to it.
Class A and axis systems are created
FOR DRAFT ANALYSIS:
First we analyze the model and then choose the dummy axis in x and y direction. As we intersected to proceed we observed that the side walls are not given any draft. Hence we assume the axis is normal to the base surface and parallel to side walls. This surely will create problems because a minimum draft has to be provided. 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 Switch Bezel Design for practice. Now we go to draft analysis and follow the usual procedure to do the analysis. 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. 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 z axis to compass direction. The axis will align itself accordingly.
NOTE: as the side wall does not have draft, this result was expected and few areas need correction. But still we are moving forward to
complete the model.
DRAFT ANALYSIS
FOR CLASS-B SURFACES
We have divided the entire model into base, side walls, inside side walls and outer flange and worked on them one by one everywhere we follow the same procedure i.e. extract, un-trim, extrapolate, trim and offset. First base, then side walls. To avoid confusion, we trimmed both together and made them one. Also the fillet was given.
Trimmed both together and made them one and fillet the edges.
FOR CLASS-C SURFACES
In this model, unlike the earlier models, we have used a parallel tooling axis. Hence we cannot use ‘with draft direction’ option under
sweep. The C surfaces will mostly be created like shown below.
FOR FINAL MODEL
Join class-A and class-C surfaces together.
Then Trim class-B surface to them.
Go to the part design and close the feature.
Run draft analysis on the model.
Below image the Red mark is of negative draft wich is less than (0.5deg) .
