Title:
NUMERICAL CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/012990
Kind Code:
A1
Abstract:
A numerical control device according to the present invention is provided with: a calculation unit that calculates a movement path for a machine tool by analyzing a machining program; an identification unit that identifies the position of a tangential discontinuity point included in the movement path calculated by the calculation unit; and an instruction generation unit that generates an instruction for specifying the orientation of the machine tool relative to the surface of a workpiece on a second movement path, with which the position of the tangential discontinuity point identified by the identification unit serves as a cutting start point, so that the relative orientation will become the same as the orientation of the machine tool relative to the surface of the workpiece on a first movement path, with which the position of the tangential discontinuity point serves as a cutting end point.
