ok here's the set up. X-2, MACH 3, Gecko 203V, KDN Tools CNC conversion (no backlash, ok I can't measure that low), 2 Flute .500" cutter, 6061 aluminum >.500" plate, Feed 20ipm, depth of cut .020", Aluminum cutting fluid liberaly applied in front of cutting path = SQUEALING
I've sped up and slowed down the cutter speed, increased and decreased the feed rate, it still persist.
Any Ideas???
Also does anyone know of a good speed feed calculator?
How do you figure "Chip Load" per tooth?
Thanks
