摘要： The present invention provides a power-supply management device which can efficiently connect and disconnect power supply to an electric-powered section, and a machine tool including the power-supply management device. The power-supply management device (101) detects a synchronization command of a control program, and compares an operation time of the electric-powered section between synchronizations in each control system which is a synchronization target by the synchronization command on the basis of the detected synchronization command. Then, the power-supply management device (101) disconnects the power supply to the electric-powered section belonging to the control system except the control system having the maximum operation time of the electric-powered section between the synchronizations, and restarts the power supply at the end of the synchronization in each control system.

摘要： A polygon machining method whereby first polygon machining is carried out on a workpiece held by a main axis, by using a polygon cutter attached to a tool main axis, then machining using a tool other than the polygon cutter is carried out, and second polygon machining after said machining is carried out, using the polygon cutter. The polygon machining method comprises: a synchronized stopping step in which the main axis is stopped at a predetermined prescribed rotation position, in a state in which the main and the tool main axis during polygon machining are synchronously rotated when the first polygon machining has been completed; a synchronization release step in which the synchronization of the main axis and the tool main axis is released when starting machining after the first polygon machining; a main axis stopping step in which the main axis is stopped at a prescribed rotation position when the machining after first polygon machining has been completed; and a synchronization starting step in which the main axis and the tool main axis are synchronously rotated when starting second polygon machining.
