Abstract
When machining a workpiece by a machine tool by cutting, a cutting fluid is sprayed to a workpiece machining region. Above a surface of the cutting fluid in a cutting fluid tank, an odor sensor for detecting the odor emitted by the cutting fluid is disposed in the space defined the surface of the cutting fluid in the cutting fluid tank and a cover. Based on the odor detected by the odor sensor, deterioration of the cutting fluid is determined.
Claims4
A state monitoring device of a cutting fluid of a machine tool, the machine tool including a cutting-fluid supplying mechanism circulating and repeatedly supplying the cutting fluid to a region where a workpiece is subjected to cutting, the state monitoring device of the cutting fluid comprising:
- an odor sensor that detects a type of odor of the cutting fluid;
- and
- a cutting-fluid deterioration handling unit that carries out a cutting-fluid deterioration handling process when an odor detection signal is output from the odor sensor.
A state monitoring device of a cutting fluid of a machine tool, the machine tool including a cutting-fluid supplying mechanism circulating and repeatedly supplying the cutting fluid to a region where a workpiece is subjected to cutting, the state monitoring device of the cutting fluid comprising:
- an odor sensor that measures and outputs odor intensity of the cutting fluid;
- a fluid-quality deterioration determination unit that compares a measured value measured by the odor sensor with a threshold value set in advance in order to determines fluid-quality deterioration of the cutting fluid;
- and
- a cutting-fluid deterioration handling unit that carries out a cutting-fluid deterioration handling process based on a determination result of the fluid-quality deterioration determination unit.
