Re: Thoughts on Gcode interpreters and CNC controls....

Darrel,

This all happened within the last year so it must have been a recent
version of Ahha. He was running a fairly fast Pentium, don't know
exactly what speed, at least 400 mhz. Ahha told us he had plenty of
processor power.

I spoke with the folks back at Ahha a couple times. They more or less
grudgingly admitted to me that their continuous contouring mode
didn't work very well. The guy had 40,000 rpm Perske spindle motors
and was hoping for some high speed contouring using 1/2" bits. Never
could get completely rid of those dwell/burns. Theoretically, with a
two flute cutter @ .010" chip load per tooth he could have contoured
at 800 ipm (is my math right?, 2x40,000x.010). By slowing the
spindle way down and a feedrate of around 20 ipm he got the best
results. From a money making standpoint that was too slow part
making.

Last I heard he went to a Centroid control and was cutting around 100
to 150 ipm.
