ABSTRACT:
In a control method and device for tapping, the phase difference between the spindle and the feed shaft at suspended positions is made equal to zero by controlling the rotation of the spindle of the feed of the feed shaft in a manner to minimize the damage on the machined portion and the rotation of the spindle and feed on the feed shaft are subsequently synchronized to reset them to their starting positions, thereby enabling an automatic reset operation.
