MACHINE MOTION TRAJECTORY MEASURING DEVICE, NUMERICALLY CONTROLLED MACHINE TOOL, AND MACHINE MOTION TRAJECTORY MEASURING METHOD |
摘要 |
A machine motion trajectory measuring device for measuring the motion trajectory of a machine used in an apparatus which controls the position of the machine by feeding back a detected position obtained by converting the rotation angles of motors for a plurality of movable axes and then driving the motors such that the detected position follows a commanded position is provided. The machine motion trajectory measuring device includes accelerometers for measuring the acceleration of the machine; and a motion trajectory measuring unit that measures the motion trajectory of the machine by obtaining the position of the machine by integrating the acceleration twice and correcting the position of the machine such that the profile of the position of the machine coincides with the profile of the detected position or the profile of an estimated position estimated using a model for simulating the response of the position of the machine to the commanded position.
