Abstract
A power saw includes a motor for driving a saw blade or the like around its rotational axis to cut a workpiece. The position of the rotational axis with respect to a reference position is sensed and a manually operated keyboard is provided for entering a desired change in the position of the rotational axis. Positioning motors are provided along with circuitry which is responsive to the entering of a desired change in the position of the rotational axis of the saw blade for moving the axis correspondingly.
