PROBLEM TO BE SOLVED: To provide a difficult-to-cut material cutting method and a difficult-to-cut material cutting device which eliminates a rise of a temperature rise and the wear of a diamond tool in the cutting of highly-hard and brittle materials such as a die material, optical glass, and a single-crystal material. SOLUTION: In an ultraprecision cutting process, the cutting method makes the center of curvature 5 of a cutting tool 4 having an arcuate cutting blade 3 and the center 10 of a rotary table 9 of a B-axis of a machine to which the cutting tool 4 is attached coincide with each other, and oscillates the rotary table 9 to always move a cutting point of the cutting tool 4 on an arc. The cutting method measures in advance an error in the depth of cut to be caused by the oscillation of the cutting tool 4 during the oscillation of the rotary table 9 and correctively controls the machine using an NC program based on the error data.
