METHOD FOR SETTING CUTTING PROCESSING CONDITIONS FOR HEAT-RESISTANT ALLOYS AND METHOD FOR CUTTING PROCESSING HEAT-RESISTANT ALLOYS

摘要

A method for setting cutting processing conditions for heat-resistant alloys that sets cutting processing conditions when cutting heat-resistant alloys using a cutting tool, wherein: the cutting tool has a shaft that is long in the axial direction and is mounted to a main spindle, and a plurality of cutting edges provided on the outer circumference of the shaft; the cutting processing conditions include a radial cut volume in the radial direction of the cutting tool; and the cutting tool radial cut volume Rd is set to be greater than a minimum radial cut volume Rd_min and less than a maximum radial cut volume Rd_max (step 22), where the minimum radial cut volume Rd_min is the radial cut volume in which one cutting edge from the plurality of cutting edges is always in contact with the heat-resistant alloy and the maximum radial cut volume Rd_max is the radial cut volume in which three or more cutting edges from the plurality of cutting edges are not in contact with the heat-resistant alloy.
