MOTION EVALUATION METHOD, EVALUATION DEVICE, PARAMETER ADJUSTMENT METHOD USING SAID EVALUATION METHOD, WORKPIECE MACHINING METHOD, AND MACHINE TOOL

摘要

In this motion evaluation method, which uses a circular motion test to evaluate motion characteristics of a numerically controlled machine tool, a normal direction change rate of a trajectory is calculated from a circular motion trajectory, the normal direction change rate of the trajectory is displayed in polar coordinates, and the motion characteristics of the numerically controlled machine tool are evaluated.
