Abstract
First and second motors are provided for moving a workpiece support in an up and down direction and and for rotation about an axis. Third, fourth and fifth motors are provided for moving a rotating cutter in a lateral direction, for rotating the cutter about an axis, and for moving the cutter toward and away from a workpiece. A first conductive pin sensor senses workpiece parameters. A cutter motor rotates the cutter at constant speed, and a second sensor senses changes in cutter motor torque when the cutter comes into contact with a workpiece. A computer includes a memory for storing instructions for cutting a desired pattern, and the computer causes the first, second, third, fourth and fifth motors to vary the relative position of the cutter and workpiece support to cut a pattern in the workpiece.
