Display device, machine tool, and liquid ejection method

A machine tool, comprising:

• a liquid ejection unit that ejects a liquid so as to move chips generated from a workpiece;
• 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;
• a display unit that displays an image captured by the imaging unit;
• a detection unit that detects a first input signal corresponding to a first position in the image displayed on the display unit, and a second input signal corresponding to a second position in the image;
• and
• a transmission unit that transmits the detected first input signal and the detected second input signal 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 position and the second position, for ejecting a liquid, based on the liquid ejection path,
• wherein the display unit displays (a) the image captured by the imaging unit, (b) the first position, (c) the second position, and (d) the liquid ejection path in a superimposed manner, the liquid ejection path connecting the first position and the second position.

A liquid ejection method for ejecting a liquid so as to move chips generated from a workpiece, the method comprising steps of:

• displaying a captured image;
• detecting a first input signal corresponding to a first position in the displayed image, and a second input signal corresponding to a second position in the displayed image;
• and
• transmitting the detected first input signal and the detected second input signal, for generating a control signal that controls to create a liquid ejection path in the target area, based on the first position and the second position, for ejecting a liquid, based on the liquid ejection path,
• wherein the display unit displays (a) the image captured by the imaging unit, (b) the first position, (c) the second position, and (d) the liquid ejection path in a superimposed manner, the liquid ejection path connecting the first position and the second position.
