Abstract:
A high speed positive feed drill motor open loop control system. The motor system comprises a minimally limited inertia air turbine motor including mounting guidance and control for enabling the drill to advance into the workpiece at a rate exactly proportional to the rotational speed of the drill. The turbine speed is measured with a digital tachometer while a stepper motor/ball screw mechanism is utilized to control and apply the feed rate.
