Thanks for the reply. It was just a general question. I've got stuck in my mind, the image of the lathe turning as "turning a super fine thread", and was wondering if it stopped when it got to the shoulder and retracted, would it leave that part of the "thread" that it didn't get around to machining. Would a standard gcode program for turning dwell to cut a complete revolution?
