摘要： The objective of the present invention is to generate a new tool path quickly by means of a simple calculation formula without calculating an approximated curve and the like. A tool path is generated with procedures that include: a distance calculation procedure, whereby one of the processing points (Pi) on a multiple rows of tool paths (PA) obtained by connecting multiple prescribed processing points sequentially with straight lines is set as a revision processing point (Pt), points on the multiple rows of tool paths in the vicinity of this revision processing point (Pt) are set as distance calculation points (Pu), and the distance (L) from the revision processing point (Pt) to each of the distance calculation points (Pu) is calculated; an extraction procedure, whereby the distance calculation points (Pu') for which the distance (L) calculated by the distance calculation procedure is within a prescribed value (”L) are extracted; a mean value calculation procedure, whereby the mean values of the position data for the distance calculation points (Pu') extracted by the extraction procedure and the position data for the revision processing point (Pt) are calculated; and a data revision procedure, whereby the position data for the revision processing point (Pt) is revised by means of the mean values calculated by the mean value calculation procedures, and a new tool path (PA') is created on the basis of the position data for the revised processing point (Pt').
