My mind is wandering this morning as I'm turning out a batch of small parts. I know, dangerous but sometimes that's when my brain spits out ideas.
As I was cranking the handle, watching the chip curling off during the gazillionth facing cut I thought "Man I wish I had a CNC lathe with spindle speed/diameter compensation" or whatever it's called when the spindle automatically speeds up to keep the SFM constant.
Then I thought if I had a variable speed setup on my lathe spindle, (treadmill motor/controller or whatever) how hard would it be to rig an encoder to the crosslide or from a DRO output into the motor controller to make an automatic speed increase as it travels across. Seems like that should be a fixed relationship and fairly easy for you guys that understand electrons and magic smoke. What say ye expurts?
Since they're ain't nuthin' new in this world, it's probably been done before, yes?
