OPTIONS OF REAL TIME MONITORING METALWORKING FLUIDS
The article is focused to describing the current monitoring systems for cutting liquids used in turning, drilling, milling and grinding operations. Based on the findings, a proprietary monitoring system is designed. The monitoring system consists of the hardware and software parts. The hardware part is a data acquisition device that contains sensors of concentration, conductivity, acidity and temperature. The device is located in the machine tank reservoir with cutting fluids. The Software section – The application displays current real-time information and a historical overview of the measured quantities. The application allows setting of limit values for monitored quantities and, if overtaken, it can alert the operator. The proposed device represents a simple way to control selected fluid properties during their life cycle.
