WORKPIECE MACHINING METHOD, MACHINE TOOL, TOOL PATH-GENERATING DEVICE AND TOOL PATH-GENERATING PROGRAM

摘要

A workpiece machining method that machines a workpiece surface (60) by moving a rotating tool (54), which has a cutting blade (54a) for interrupted cutting of the workpiece surface (60), relative to the workpiece (6) comprises: a first process of determining the pattern of arrangement of multiple cavities (610) on the surface of the workpiece formed after cutting by the cutting blade (54a); and a second process of determining the tool path (PA) of the rotating tool (54) so that the multiple cavities (610) are disposed on the surface of the workpiece according to the pattern of arrangement determined in the first process.
