Method for NC- programming and system for NC- machining

An NC machining system comprising the steps of:

• producing a measurement program for measuring machining quality of a workpiece machined by a machine tool using a measuring machine through analyzing an NC program for carrying out machining control of the machine tool for the workpiece;
• measuring machining quality of the workpiece using the produced measurement program and the measuring machine;
• and
• judging machining quality of the workpiece by comparing the measurement results of machining quality of the workpiece measured by the measuring machine and machining quality information included in the NC program, the machining quality information regarding machining quality after machining a workpiece.

An NC machining apparatus comprising:

• means for producing a measurement program for measuring machining quality of a workpiece machined by a machine tool using a measuring machine through analyzing an NC program for carrying out machining control of a machine tool for a workpiece;
• a measuring machine for measuring machining quality of a workpiece using the produced measurement program;
• and
• means for judging machining quality of the workpiece by comparing the measurement results of machining quality of the workpiece measured by the measuring machine and required machining quality information included in the NC program, the machining quality information regarding machining quality after machining a workpiece.
