Variable pitch screw
« on: August 01, 2008, 08:08:57 PM »
Looking for some info on how to program such a monster. It has become a tough task trying to create a 3d model in TurboCAD v15 Professional Mechanical to generate the code from. But I think I may be over complicating it. I am begining to think it would be easier to code by hand, I just need a starting point.
I know this was a very vague post, I am merely trying to understand what needs to be done. The screw I will cut will made from UHMW or Delrin with a stainless steel thru shaft, the machine I will cut this on will be a CNC router (to be built or bought in the near future) with a 4th axis. I may be building one if I do not get one purchased soon, as of now I have no machine specs, just looking for theory.

here is a link to the turbocad user forum thread on this subject http://forums.imsisoft.com/forums/Thread.cfm?CFApp=200&Thread_ID=65100&mc=24
Can anyone help?
