ABSTRACT:
(A) V-CAD data of an object (1) is prepared. (B) A processed surface shape after NC processing is predicted by simulation using the V-CAD data. (C) The object is subjected to NC processing by a predetermined NC program, and a processed surface shape after NC processing is measured, and (D) processing correction data is obtained from a difference between the processed surface shapes acquired by simulation and measurement, and the NC program is corrected based on the processing correction data. As a result, the ultra-precise processing is enabled even if a workpiece or a tool has low rigidity and an inconstant quantity of deformation.
