Display device, machine tool, and liquid ejection method

Abstract

A display device, a machine tool, and a liquid ejection method with which a liquid ejection path for efficient chip removal can be created, without performing huge control process. The display device is for displaying an image in order to eject a liquid and move chips generated from a workpiece in a machine tool. The machine tool includes a liquid ejection unit that ejects a liquid so as to move chips generated from a workpiece, and an imaging unit that captures an image of a target area in which chips generated from a workpiece are to be detected in the machine tool. The liquid is ejected to the target area, based on a first position and a second position in the image captured by the imaging unit. The display device includes: a display unit that displays an image captured by the imaging unit; a detection unit that detects a first input signal corresponding to the first position in the image displayed on the display unit, and a second input signal corresponding to the second position in the displayed image; and a transmission unit that transmits the detected first and second input signals to a signal generation unit, the signal generation unit generating a control signal that controls to create a liquid ejection path in the target area, based on the first and second positions, for ejecting a liquid, based on the liquid ejection path.
