I'm running parts that weigh thousands of pounds and they stick out so far I struggle to control chatter the only solution I've found is to stand there for 30 min and go from 80-150 spindle speed back and forth.

I see okumas and haas have ssv or hssc options built in but I'm not as familiar with mazak. I'm running a mazak Slant turn 60N. And all the programs I'm given are fanuc controls.

I'm not sure how to adjust for that or if I even can. Would need step by step if possible. If I have to adjust variables or parameters or something.
