General Mach Discussion / Re: Probing speed
« on: November 14, 2018, 07:16:28 AM »
John,
I probe at 1in/min in Mach3 when setting lathe tools and only one touch off is used.
Yes, that is slow, BUT, accuracy is +-0.0002", repeatable. Overall time to populate
a tool table for 20 different type lathe tools takes under/about 20 minutes.
Probe feedrates need to address the users configuration, system accuracy, which include software reaction time, and axis accel/ decel time.
Probing should not cause damage to part or tool. Must also say that any probing will only be as accurate as the users machine "system".
Probe feedrate should be an a user defined rate depending the what the probed values will be used for. If I recall correctly min slow probe distance for Mach3 must be greater than 0.010".
I also probe to acquired points to automaticaly make a CAD drawing of a part. The rate varies depending the routine that will be used.
Variables associated with probing should be user adjustable / defined if the probing is not dedicated to a specific system.
FWIW,
RICH
