ABSTRACT:
In an numerical control machining system, a plurality of parts on a work are cut into predetermined shapes with one cutting tool by moving back and forth the cutting tool a plurality of times for each part to be cut. When determining a tool running path, a cutting trajectory of the cutting tool for each of the parts is obtained, all the end points of the cutting trajectory which can be a tool inlet end or a tool outlet end for each of the parts are stored, the part the cutting trajectory for which has an end point which is the nearest to the tool outlet end of the cutting trajectory for one of the parts as measured along the path of movement of the tool is determined to be the part to be cut next, and said nearest end point is determined to be the tool inlet end of the cutting trajectory for the part to be cut next.
