I plan to use spindle speed control in my part programs. I also would like to use the best spindle gear selection for the proper cutting speed and to best utilize the horsepower I have available. If my part program sets a spindle speed of 500RPM, how will EMC2 handle it if I'm in a gear where top speed is 600RPM vs a gear where top speed is 1800RPM? I guess my basic question is do I have to define my top speed for each spindle gear change? Is this done in the part program, perhaps similar to a tool change?
