So we Turn, chucking on to a (304ss) 4ft long, 5in diameter part with a 1.25" diameter shaft 8" long, centered, in a CNC with tailstock.
Trouble is, when turning the small shaft for a bearing fit, there is a LOT of chatter. I suppose the solution for the past umpteen years has been to have the operator toggle the speed/feed override continuously, which works "well enough" ...
Lathe is a 1998 Yang, Fanuc, turret type with tailstock, no accommodation for a steady or follower.
Is there a way to simulate the toggling from a programming perspective, akin to having it ride some sine wave perhaps? I'm running it now and would love to fix this age old problem while sparing my hands.
