Abstract
A numerical value control device controls a machine tool in which a multi-edge tool for turning is used to turn a workpiece, and said numerical value control device includes: an NC command decoder unit that decodes a command of a processing program; and a tool information generation unit that generates geometric information pertaining to the multi-edge tool. The NC command decoder unit includes: a tool path generation unit that calculates the tool path from the command of the processing program; an edge switching determination unit that determines whether or not the edge of the multi-edge tool needs to be switched; an edge switching path generation unit that calculates an edge switching path including a retracting path for switching the edge, the rotation direction and rotation amount of the multi-edge tool, and a returning path; and a tool path regeneration unit that binds the edge switching path to the tool path.
