摘要: Method of machining an area (AR) surrounded by outline curve (OLC) and a plurality closed curves (INC1 INC2) unidirectionnal cutting technique or reciprocative technique. The method includes: step calculating first second offset (INF1 INF2) which are obtained outwardly offsetting the respective amount corresponds to tool diameter; intersections (Ri Ui) between each i th path (PTi); moving (TL) from start point (Pi) (PTi) along while effecting as far (Ri) two Si) (INF1); of, when intersection (Si) is present inside (INF2), that (Ui) (Ti passage not no operation; end (Qi) cutting.
