Display device for machine tool

Abstract

Provided is a technique whereby overlapping of a tool path of a machine tool that uses a plurality of tool blades can be easily perceived in a display device for a machine tool. A display device 1 for a machine tool comprises a first tool path acquisition unit 12 that acquires relative first tool path information of a workpiece and a tool based on a relative rotation angle of a workpiece and a tool due to a first tool blade, a second tool path acquisition unit 13 that acquires relative second tool path information of the workpiece and the tool based on a relative rotation angle of the workpiece and the tool due to a second tool blade, and a display control unit 14 that displays a first tool path indicating a path of the first tool blade and a second tool path indicating a path of the second tool blade on the same display unit 20 on the basis of the first tool path information and the second tool path information.
