ABSTRACT:
The numerically controlled machine tool provided with an automatic tool exchange device and a work indexing device. After the spindle head completely retreats, the preparation for the next tool, the exchange of the tools or the change of the machined surface are carried out. Since the interference region at the time of the change of the machined surface is determined, the tools can be exchanged closest to the work but without interfering with the work. The indirect operation time required for the exchange of the tools and the change of the machined surface can be minimized. When the work has multiple surfaces to machine, the work can be rotated minimum angle in a predetermined direction without interfering with the peripheral device by the indexing device to change the machined surface. The operator can confirm the direction on the display.
