Abstract

A control apparatus for a shaping machine such as a lathe includes a positionable piston and cylinder assembly for driving the cutting tool toward the workpiece to establish cut depth. A feeler rides a pattern to limit cut depth and control cut shape. A plurality of cam-operated switches responsive to piston and cylinder assembly position controls cut depth in successive cycles until control is assumed by the feeler. The feeler operates switches and a control valve to permit close control of the shaping in accordance with the pattern.
