<p>A tool path determination method is employed to determine a tool path (ES) from an approach point (Pa) to a start point (Ps) of a first machining path (PF). The method comprises: a first step of inputting data ( l 1, xs, ys; a, xs, ys) specifying a predetermined tool path pattern from a plurality of tool path patterns and also specifying the approach point (Pa); a second step of calculating coordinates (xa, ya) of the position of the approach point (Pa) by employing an operational expression corresponding to the specified tool path pattern and the data specifying the approach point; and a third step of determining the tool path (ES) from the approach point (Pa) to the start point (Ps) of the machining path (PF), on the basis of the approach point and the specified path pattern.</p> |
