Abstract
A five-axis control machine tool stores rotation-axis data indicating the inclination or runouts of each of a rotation axis A of a tilting table and a rotation axis C of a rotating table in association with rotation angles determined based on NC data, and calculates a correction rotation angle of each of the rotation angles A and C to correct the erroneous attitude of a tool. Five-axis control is performed based on the NC data by rotating the tilting table and the rotating table about the rotation axes A and C at the correction rotation angles, so that a workpiece is machined while eliminating the erroneous attitude of the tool.
