摘要： A method and apparatus for fast threading pullout in a numerically controlled threading application which includes position determining logic for receiving position command signals from a numerical control and determining the commanded movement of a threading member along at least a primary threading axis and a secondary pullout axis, at least one sensing device for sensing the position of the threading member along at least the primary and secondary axes, velocity calculation structure for generating velocity command signals for actuating the threading member along the primary and secondary axes in accordance with the commanded movements and the sensed position of the member, supplemental velocity structure for applying a supplemental pullout velocity at a predetermined pullout position on the thread to accelerate the member along the secondary axis, and monitoring logic for monitoring the pullout of the threading member along the secondary axis and discontinuing the supplemental velocity after a predetermined portion of the pullout.
