Control method, control device, and machine tool

Abstract

The present invention provides a control method, a control device, and a machine tool that can improve the chip-breaking effect by optimizing the oscillation in accordance with the mass of the oscillating part. [Solution] The control method includes: a first step of acquiring machine control parameters that minimize the difference between the lower limit relative movement speed and the actual lower limit relative movement speed in multiple mass states in which multiple reference masses are added to the table 20; a second step of generating a first experimental information table T1 consisting of a combination of multiple reference masses and corresponding machine control parameters; a third step of acquiring mass information of the table 20 when the machine tool 10 performs oscillating hole machining; and a fourth step of acquiring machine control parameters corresponding to the mass information from the first experimental information table T1 and setting them as machine control parameters for oscillating hole machining.
