<p>A method of machining the inside of an area (AR) surrounded by a closed curve (OFC'). The method includes: (1) the step of calculating the centroid (W) of the area (AR) surrounded by the closed curve (OFC'); (2) the step of deciding whether or not each of the line segments (L1 to L10) respectively connecting the centroid and the vertexes (P1 to P10) of the area crosses the closed curve; the step (3) of, if each of the line segments does not cross the closed curve, dividing each of the line segments into a predetermined number of partitions; (4) the step of moving a tool along a plurality of closed paths (CPT1, CPT2 ...) each formed by connecting the corresponding points of partition of the respective line segments, thereby effecting an area machining operation; and (5) the step of, if at least one of the line segments crosses the closed curve, dividing the area (AR) into a plurality of regions, calculating the centroid of each of the divided regions, dividing each of the line segments into a predetermined number of partitions, the line segments being respectively formed by connecting each of the centroids and the vertexes of the divided region corresponding to that centroid, calculating a plurality of closed paths, each formed by connecting the corresponding points of partition of the respective line segments for each of the divided regions, and successively moving the tool along each of the closed paths, thereby effecting an area machining operation.</p> |
