摘要： In a numerical control machining system, a leftover area on a work produced by cutting the work with a larger diameter ball end mill is cut with a small diameter ball end mill. When the cutting trajectories of the small diameter ball end mill are determined, the leftover portions are identified in the directions of the cutting trajectories for the larger diameter ball end mill which are set at regular pitches and reference cutting trajectories for the small diameter ball end mill which are the cutting trajectories when cutting the leftover portions with the small diameter ball end mill in the direction of the cutting trajectories for the larger diameter ball end mill are obtained. The reference cutting trajectories are divided at the same number of points at regular intervals in the direction of the reference cutting trajectory, and the lines obtained by plotting the corresponding dividing points on the respective reference cutting trajectories by straight lines are determined as the cutting trajectories for the small diameter ball end mill.

摘要： 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.
