Classification: CPC G | IPC G

Claim 6:
7. A numerical control device to machine a workpiece while performing vibration cutting in which a tool and the workpiece are relatively vibrated by driving a first axis to drive the tool or a second axis to drive the workpiece, the device comprising:
parameter adjustment circuitry to adjust a parameter related to a vibration condition for the vibration cutting during the vibration cutting, based on an amount of cutting load that is generated on the first axis or the second axis—and changes during the vibration cutting; and
controller circuitry to control the vibration cutting using the adjusted parameter, wherein
the parameter adjustment circuitry calculates the parameter with which an estimated value of an air-cutting amount at a time when the tool cuts air with respect to the workpiece during the vibration cutting becomes a minimum air-cutting amount greater than zero.
