A complex machine tool has a single frame having a chip collecting space at a center portion thereof, first and second spindle stocks on the frame, relatively free to move and drive in a Z axis direction and holding the chip collecting space therebetween, workpiece spindles on the spindle stocks free to rotate and drive and facing each other, and tool rests. The tool rests have turrets and can assume various kinds of movement. Complicated and varied types of machining can be performed combining the rotation control of the workpiece spindles and the spindle stocks.

Complex machining machine tool

In a machine tool having plural coordinate systems and having controlled objects controlled on the basis of those coordinate systems, a coordinate system data memory storing dimensional information corresponding to each coordinate system as a coordinate system data is provided. A coordinate relation memory storing the coordinate position relation information by which the position relation among plural coordinate system is specified is also provided. If the controlled object corresponding to each coordinate system is driven, the coordinate system data is read from the coordinate system data memory when the coordinate system data belonging to the coordinate system except the coordinate system in which the controlled object is driven is needed. The read coordinate system data is converted from the coordinate system to which the corresponding coordinate system data belongs into the other coordinate system to which the controlled object belongs on the basis of the coordinate position relation information in the coordinate relation memory, and the controlled object is controlled on the basis of the converted coordinate system data.
