Hi Art,
Thanks, but in the example of running at 2000 rpm with the Z axis
needing to move at 100ipm, it would take only 1/100th of a minute to
cut a one inch long thread. I haven't done any calculus for a long
tome but it seems to me that I'd have to start way before the thread
and the deceleration would still ruin it.
If I'm right what kind of Z axis acceleration would one need to be
able to cut at that speed?

Hi Jerry:
The 3.5 would be units/sec/sec in other words in one second it
will be
doing 3.5*60 units per minute or 210 units per minute, so it takes
about 1/2
second to get to speed of 100..
