NUMERICAL CONTROL DEVICE, NUMERICAL CONTROL METHOD, AND MACHINE LEARNING DEVICE

WIPO Patent Application WO/2020/110251

A1

A numerical control device (1X) for controlling: a main shaft (60) which constitutes the axis of rotation of a workpiece (70); a drive shaft (61X) which drives, in the X-axis direction, a tool (66A) for performing vibratory cutting on the workpiece (70); and a drive shaft (61Z) which drives the tool (66A) or the workpiece (70) in the Z-axis direction. The numerical control device (1X) comprises: a storage unit (34) which stores a machining program for performing vibratory cutting on the workpiece (70); and a control calculation unit (2X) which, on the basis of a tolerance value that is an error permitted when performing corner machining on the workpiece (70), calculates a specific point through which the tool (66A) passes at the time of the vibratory cutting, and generates a vibration waveform for the tool (66A), said vibration waveform representing the path of movement of the tool (66A) when the tool (66A) passes through the specific point, wherein the control calculation unit (2X) controls the movement and vibration of the tool (66A) in accordance with the machining program and the vibration waveform.
