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

摘要

In a method of setting heat-resistant alloy cutting conditions used to set cutting conditions under which a heat-resistant alloy is cut with a cutting tool, the cutting tool has a long shaft mounted on a spindle and extended in the axial direction and a plurality of teeth formed on the outer circumference of the shaft. The cutting conditions include a radial direction cutting amount of the cutting tool in the radial direction. When the radial direction cutting amount in which one of the teeth of the cutting tool is constantly in contact with the heat-resistant alloy is given as a smallest radial direction cutting amount Rd_min and the radial direction cutting amount in which three or more teeth of the teeth are not in contact with the heat-resistant alloy is given as a largest radial direction cutting amount Rd_max, a radial direction cutting amount Rd of the cutting tool is set in the range from the smallest radial direction cutting amount Rd_min to the largest radial direction cutting amount Rd_max (Step S22).
