摘要： A command-value generation apparatus includes: a segmentation unit to segment a machining program into execution units to generate segment machining programs; a parallel computation unit, including a plurality of arithmetic units, to execute the segment machining programs on a per execution unit basis in parallel and generate a segment command for each of the execution units, the segment command being a group of interpolation points on the tool path; and a command-value generation unit to generate a tool travel command from the segment command for each of the execution units. The segment machining programs are separate from one another by at least one segmentation point. The segment machining programs includes a forward segment machining program located forward of the segmentation point, and a rearward segment machining program located rearward of the segmentation point.

摘要： A numerical control device that controls, in a machine tool, driving of a motor based on a machining program is provided. The numerical control device includes a position-command generating unit configured to generate a position command to the motor and a mark-command generating unit configured to generate a mark command for machining of a mark indicating that an abnormality occurs in the machining. The mark-command generating unit sequentially stores information concerning a moving route of the tool by the machining and generates, when an alarm is raised because the abnormality is detected, as the mark command, a moving command for moving the tool in a direction opposite to a direction during the machining while correcting a position of the tool in a tool axis direction with respect to a position during the machining, and the position-command generating unit generates the position command based on the mark command.

摘要： A tool-path correcting apparatus includes a cut-point calculating unit that calculates, on the basis of tool path data, tool data, and shape data, cut point information, which is information concerning cut points by a tool on a machining curved surface of a machining shape at the time when the tool is disposed at command points described in the tool path data, a correction-command-point extracting unit that extracts, on the basis of the tool path data and the cut point information, correction command points, which are command points that should be corrected, from command points described in the tool path data, a command-point-correcting-direction determining unit that determines, on the basis of the correction command points, command point correcting directions, which are directions in which the correction command points should be corrected, and a tool-path-data correcting unit that corrects the tool path data.
