PROBLEM TO BE SOLVED: To surely prevent chips from sticking to an inner peripheral surface of a cutter drum on a crankshaft miller for a long term. SOLUTION: In the crankshaft miller 1 for successively carrying out a plurality of cutting steps on a workpiece 5 by a cutter 55 mounted on a cutter drum 41 rotated at prespecified machining rotation speed VH, rotation speed of the cutter drum 41 is once decreased from the machining rotation speed VH to non-machining rotation speed VL during a non-machining period between a cutting step previously taking place by the cutter 55 and a subsequent cutting step.
