Second Generation Cam
Mood:  caffeinated
Topic: Cam

This is a rough draft of the the second generation cam illustrating how the transition area was not enough.

There are a number of mathematical areas that have to be geometrically proven.  It is a given that there is a double helix spiral.  But there is another geometric feature that has to be proven.  On top of that there is two other geometric features on top of that.  All of a sudden we are getting into multi dimensional problems.

When I asked Jim how do you verify if the program works?  He said all you have to do is put the two cams together and see if there is any gaps.  I knew it was geometrically correct because I never failed to provide my high school geometry teacher the correct proof of any challenge geometry problem.  I thought that was worth at least an A...but all he gave me was a B....   :)

Shopping around for CAD/CAM/CAE software.  I was impressed on how ProEngineer was able to model the original cam profile.  I may do a simulation on the infinite acceleration but we already know that this version did not work.
