Mach requires one pulse per rev, an index, to calculate and synchronise a thread. Mach assumes that the speed is constant even when the tool engages the
material and starts cutting. We all know that is never actually the case, the spindle always slows a little. Even with closed loop control a feedback of one pulse
per rev is not enough for a controller to maintain spindle speed accurately enough for threading.
Sorry Craig but this is not quite true - there are many lathe users threading this way.
