NC machine tool apparatus having means for producing NC work program and method thereof

An NC machine tool system comprising a first NC machine tool apparatus and a second NC machine tool apparatus connected to said first NC machine tool apparatus,

• said first NC machine tool apparatus comprising:
• a first NC machine including at least one spindle to which a tool or a sensing device is attached, and a drive mechanism for driving said spindle, and
• a first control unit for controlling said drive mechanism, said control unit comprising an NC work program producing means for producing, in accordance with a source work program, an NC work program for machining a workpiece, said source work program specifying a pattern to be machined on said workpiece, said NC work program producing means controlling said drive mechanism, in accordance with said measurements;
• and
• said second NC machine tool apparatus comprising:
• a second NC machine having at least a second spindle to which a second tool is attached, and a second drive mechanism for driving said second spindle;
• and
• a second control unit controlling said second drive mechanism said second control unit comprising:
• means for inputting said produced NC work program from said first control means;
• and
• a machining execution means for executing the machining of a workpiece held in said second NC machine in accordance with said input NC work program.

A machine tool apparatus comprising:

• a machining machine including at least one spindle to which a sensor device is attached, and a drive mechanism for driving said spindle;
• and
• a control unit for controlling said drive mechanism, said control unit comprising:
• a source work program which defines a predetermined pattern;
• and
• a program producing means for executing said source work program and creating a first NC work program for machining a first workpiece, said program producing means controlling said NC machine to move said sensing device attached to said spindle in accordance with said pattern and measuring said workpiece, said program producing means creating a first NC work program for controlling said drive mechanism in accordance with said first measurements.
