Abstract
A cutting machine is provided with a machine main body and an NC device. The NC device controls the machine main body and has a tool radius compensation amount calculation unit, a machining path calculation unit, and a drive control unit. The tool radius compensation amount calculation unit generates tool radius compensation information. The machining path calculation unit generates a tool radius compensation control signal. The drive control unit generates a drive control signal. The machine main body has a machining unit and a tool path control unit. The machining unit cuts a workpiece by changing a relative position thereof with respect to the workpiece. Based on the drive control signal, the tool path control unit controls a tool path corresponding to a cutting tool and having a non-circular shape.
