ACCELERATION AND DECELERATION CONTROL METHOD FOR MOVING OBJECT, AND NUMERICAL CONTROLLER USING THE METHOD

摘要

PROBLEM TO BE SOLVED: To shorten the accelerating and decelerating time by making the capability of each axis exhibited to the maximum at the time of simultaneous two axial control. SOLUTION: Which of the acceleration and deceleration of a first moving object and that of a second moving object is larger is judged from a commanded orbit at the time of the simultaneous two axial control of a moving object, and a position command for accelerating and decelerating the moving object whose acceleration and deceleration is judged to be larger at a maximum acceleration and deceleration Aymax is obtained. Then, the position command of the moving object whose acceleration and deceleration is judged to be smaller is obtained so that the commanded orbit can be maintained for the obtained position command, and the moving object is controlled based on each obtained position command.
