Jones and shipley cylindrical grinder CNC conversion, grinding camshafts, cranks

I have actually found 4 companies that make software, 1 of them is relatively affordable. The issue again becomes generating tools path. I am curious about the Freecad work offset bench however. does freecad support 4th axis or C axis work ? I was considering adding a indicator with a radius foot that could act as a encoder onto a set of centers I have laying around with a encoder to grab the pertinent data. Very open to ideas on all of this BTW. the air cutting issue isn\t that big of a deal. If I can figure out how to generate the roughing profiles on the C axis, I can add a spindle to my lathe, rough turn the camshaft and then rough in the cam lobes. Stand it up and drill the ends or do it as a C-axis drilling open for the locating pin or bolt up.

I am very open to suggestions on all of this BTW  

I'd think you'd want to put the gear holes, and especially the registration hole(s), in the end before you start grinding lobes.  Even with adjustable timing pulley/gears you still need all the lobes to be referenced to something.

Do you have a good workhead for your grinder?  I picked up a surplus high-end grinder work spindle that I was thinking of turning in to a lathe headstock, but that's not likley to happen as it has no through-bore.  I could make you a sweet deal on it... quad AC bearings and runout is not measurable on a 50-millionths indicator.
