Abstract
A machine tool setting device and control system are provided. The machine tool setting device sets the machine tool tip at a predetermined distance above a work piece by detecting when the machine tool tip intercepts an optical beam. The control system allows for the drilling of multi-ply work pieces wherein the multi-plies comprise different thicknesses and hardnesses. The drill bit translational velocity and rotational velocity are continuously controlled for optimization depending upon the type of material and thickness as a hole is drilled through the work piece.
