摘要： A CNC controlled rotating workpiece holding fixture is attached to a tombstone of a horizontal mill. The rotating workpiece holding fixture(s) allows workpieces to be independently rotated to allow milling of various surface of the workpiece thereby providing a five axis CNC capability. As many as eight rotating workpiece holding fixtures may be attached to a single tombstone. Each rotating workpiece holding fixture may be formed by a harmonic drive driven by a servo motor which provides a compact configuration and a very low gear ratio in the harmonic drive combined with the inherent braking of the servo motor provides stability. The rotating workpiece holding fixtures may be controlled using existing auxiliary outputs (e.g., M-Codes), present in CNC milling machines. The M-Codes are preferably created by an operator, multiplexed, sent to the tombstone, de-multiplexed, and used to control each rotating workpiece holding fixture.
