MACHINE TOOL CONTROL DEVICE
20240012386 · 2024-01-11 · ·

The present invention provides a machine tool control device that makes it possible to optimally adjust a variation condition and obtain a stable chattering suppression effect. The machine tool control device is provided with: a variation command calculation unit that calculates a variation command on the basis of a speed command for a spindle motor in a machine tool and a variation condition for varying the rotation speed of the spindle motor, and generates a speed control command for controlling the speed of the spindle motor on the basis of the speed command and the variation command; a speed deviation determination unit that determines whether or not a speed deviation indicating the difference between the speed command and the actual speed of the spindle motor in a prescribed period is within a first permissible range; and a condition change unit that changes the variation condition when the speed deviation is out of the first permissible range.
