The invention relates to a
servo tool
magazine tool changing control method. During the rotating process of a tool arm, a tool is loosened and broached in advance, so that the
waiting time after the tool arm is in place is saved, and the tool changing speed is increased; for tools with different weight, the larger the current value or torque value of a
servo drive motor is, the tool is heavier, and the smaller the current value or torque value of a
servo drive motor is, the tool is lighter. In the tool changing step, the rotating speed of the
servo drive motor is adjusted by detecting the current value or torque value of the
servo drive motor to change a larger tool and a heavier tool at a lower speed and change a smaller tool and a lighter tool at a higher speed, so that
centrifugal force during rotation of the tool can be effectively controlled, and the
servo drive motor is prevented from damage under action of
centrifugal force of the tool when drives the tool to rotate; and in addition, the rotating speed is set according to tools with different weight to reduce or avoid
impact generated when the tool is positioned to improve the
machining precision.
