Complex machining machine tool

A complex machining machine tool having a tool rest capable of attachably and detachably receiving a complex tool having a plurality of inserts thereon, the complex tool being capable of a plurality of kinds of machining operations on a workpiece by selectively indexing and using a selected one of said inserts on said complex tool, said complex machining machine tool comprising:

• a spindle rotatably supported and defining a Z-axis as its center;
• said tool rest being free to move and drive in an X-axis direction perpendicular to said Z-axis, and being free to rotate, position and drive in a B-axis direction with a Y-axis perpendicular to said X-axis and Z-axis as its center;
• a tool file storing tool data concerning said complex tool to be used in a machining program;
• said complex tool being registered in said tool file as a plurality of virtual tools;
• a plurality of said virtual tools being virtually set concerning said complex tool, the virtual tools corresponding to machining operations that are capable of being executed with said complex tool;
• said virtual tools including a turning tool and a milling tool;
• said tool data being stored for every said virtual tool;
• said tool data including an angle in said B-axis direction concerning each said virtual tool at which angle said virtual tool is positioned when said virtual tool is used;
• and
• machining executing means reading out the tool data corresponding to a virtual tool from said tool file on the basis of programmed machining instructions for use of said virtual tool according to a stored machining program and for executing the stored machining program with said virtual tools of said complex tool being set and selected on the basis of said tool data.
