Mechanical motion trajectory method for measuring mechanical motion trajectory measuring device, and numerical control machine tools

摘要

Trajectory of motion of the machine in an apparatus for controlling the position of the machine by feeding back the detected position obtained by converting the position of the motor rotation angle, and drives the motor of the movable shaft a plurality (1) detection position to follow the command position A mechanical motion trajectory measuring apparatus for measuring, and accelerometer (13) for measuring the acceleration of the machine, as well as obtaining the machine position by second-order integration the acceleration profile of the machine position, the machine for the command position trajectory of motion measuring unit for measuring the movement trajectory of the machine by correcting the machine position to match the profile of the detected position or profile of the estimated position estimated by the model for simulating the response of the position of a, and (14) provided.
