Abstract

PURPOSE:To make the edge of a knife coincide with a recessed part of a worked screw and to work the screw again by effectively executing manual interruption by a manual pulse generator during an automatic operation mode. CONSTITUTION:A knife edge 4 is made to coincide with a recessed part of a worked screw by moving the knife edge 4 in the X and Z directions through a manual pulse generator in an automatic operation mode and then the knife edge 4 is moved in the Z direction by the cut distance of the screw to work the screw again.
