PROBLEM TO BE SOLVED: To suppress a component blade edge by a depositedγphase and realize a long life, by optimizing a cutting condition. SOLUTION: In this method for cutting a copper alloy having at least aγphase, by assuming P for the number of tool blades, R (rps) for a rotational speed of a tool, X (mm/sec) for a feed speed, T (mm) for the thickness of the tool, and DB (mm) for the external diameter of a cut material, when the number Q of passing times of the tool blade per unit cutoff volume is as follows, the method for cutting the copper alloy having theγphase is characterized by setting as Q<1. Q=P.R/(X.T.DB).
