To provide a controller for a machining device capable of making the machining device make oscillating motion along a command route. A controller controls a machine tool comprising multiple control axes and used for machining by cutting of a work as a machining target. The controller comprises: a position command acquiring unit that acquires a position command directed to a servo motor for driving a cutting tool or a position command directed to a servo motor for driving the work; a rotation speed acquiring unit that acquires a rotation speed such as that of the cutting tool; an oscillation amplitude calculating unit that calculates oscillation amplitude based on the position command and the rotation speed; an oscillation frequency calculating unit that calculates an oscillation frequency based on the rotation speed; an oscillation command calculating unit that calculates an oscillation command based on the oscillation amplitude and the oscillation frequency; a position command storage unit that stores a command route determined based on the oscillation amplitude; an oscillation command correcting unit that corrects the oscillation command based on the command route; and a driving unit that determines a drive signal to be used for driving the servo motor based on the position command and the corrected oscillation command, and outputs the drive signal.
A controller that controls a machine tool comprising multiple control axes and used for machining by cutting of a work as a machining target by means of coordinated motion of the control axes, the controller comprising:
A method of controlling a machine tool comprising multiple control axes and used for machining by cutting of a work as a machining target by means of coordinated motion of the control axes, the method comprising:
A non-transitory computer-readable recording medium storing a computer program that causes a computer to operate as a controller that controls a machine tool comprising multiple control axes and used for machining by cutting of a work as a machining target by means of coordinated motion of the control axes, the computer program causing the computer to execute:
