NUMERICAL CONTROL DEVICE, NUMERICAL CONTROL MACHINE TOOL, MACHINING PROGRAM GENERATION DEVICE, AND MACHINING PROGRAM GENERATION METHOD

WIPO Patent Application WO/2024/013955

A1

A numerical control device (1a) is provided with: a model holding unit (13) that holds a machine model which simulates, in each axial direction that is the direction of each of a plurality of axes, a deformation of a mechanical structure caused by a motion of the machine structure and represents an error amount, which is a displacement amount of a tool in each axial direction caused by the deformation of the mechanical structure; a machining error estimation unit (12) that estimates, on the basis of axis data and the machine model, an error direction and an error amount in the error direction, said axis data being data on drive of a drive mechanism, said error direction being a direction which is of the axial directions and in which a tool displacement occurs and that outputs machining error information indicating the estimated error direction and the estimated error amount; and a correction amount calculation unit (14a) that selects, on the basis of the machining error information, one or more axes as targes of the correction and calculates a correction amount to be used to correct an instruction output to the drive mechanism for the selected axis.
