Abstract
Abstract Method and apparatus are disclosed for cutting one or more apertures in a cabinet front blank. The cutting operation is performed by a router selectively extending into and out of the cabinet front blank. The movement of the router in the X and Y axes is controlled by air operated mechanisms. A plurality of mechanical switches responsive to movement and position of the router provide feedback signals to a pneumatic control system. The control system also processes command signals from manual controls, which command signals provide direct control over the cutting operation of the router. The number, size and spatial relationship of the apertures may be programmed by the manual controls.
