Embodiment Construction

[0020] Embodiments of the present invention will be described below with reference to the drawings. In the following description, up and down, left and right, and front and rear indicated by arrows in the figure are used. The left-right direction, front-rear direction, and up-down direction of the machine tool 1 are the X-axis direction, the Y-axis direction, and the Z-axis direction of the machine tool 1 , respectively.

[0021] Refer below Figure 1 ~ Figure 4 The outline of the structure of the machine tool 1 will be described. Machine tool 1 comprises abutment 2, machine tool main body 3, cover 4, workbench 8 (refer to Figure 4 ), tool changer 13 (refer to Figure 4 ), control box 15, etc. The base 2 is a substantially cuboid iron base. The machine tool main body 3 is provided behind the upper part of the base 2 , and performs cutting processing on a workpiece (not shown) held on the upper surface of the table 8 . The types of cutting processing include, for example...

Abstract

The invention relates to a numerical control device for controlling a machine tool. The CPU of the numerical control device idles before machining of a workpiece, obtains consumed electricity of a spindle motor when the spindle rotates from a motor control part and stored the consumed electricity in RAM. After idling, the CPU performs workpiece machining. During workpiece machining, the CPU obtains consumed electricity of the spindle motor at regular intervals. The CPU calculates differences between actual machining electricity obtained at regular intervals and the idle electricity stored in the RAM, accumulates the differences calculated at regular intervals, and stores the differences in the RAM in real time. When the accumulated value exceeds base electricity, the CPU drives a pump to start ejection of a cutting spray part. The numerical control device can spray cutting liquid according to the production amount of cuttings.

Description

technical field [0001] The invention relates to a numerical control device for controlling a machine tool. Background technique [0002] The machine tool includes a cover. The cover covers the machining area of ​​the machine tool and includes a plurality of nozzles inside it. The cutting fluid is ejected from the nozzle to wash away the chips attached and accumulated in the cover. Japanese Patent Laid-Open No. 30135 of 2007 discloses a machine tool in which piping for supplying cutting fluid to a nozzle is arranged to be the shortest. As a method of cleaning the inside of the cover using the nozzle, for example, the discharge of the cutting fluid is started at the beginning of the machining program and stopped when the machining program ends. However, in the above-mentioned cleaning method, the cutting fluid is continuously sprayed once the cutting fluid is started to be sprayed. Therefore, especially in machining with few chips, the cutting fluid is sprayed in vain, and ...
