Analysis of temperature in different cooling methods

Abstract

Cooling is one of the main issues in every machining process. By cooling, we can increase the tool life of our tool and maintain the quality of our surface. There are many options in the industry. A wide variety of cooling lubricants are available. There are general requirements for cooling and lubricating fluids used during machining, such as good thermal conductivity, proper lubrication, protection of workpiece and tool against corrosion, anti-foaming or stability during storage and use. These parameters are extremely important for the machining process, so you should be careful when selecting the coolant fluids. In our article we would like to introduce a measurement method, a measuring arrangement, with which we tested many coolant lubricants. Our main aim will to show that the MQL (Minimum Quantity Lubricant) technology is how better than the other cooling method. We used different types of cooling lubricant. Among our choices are mineral oils, synthetic oils, and biological degradable oils too. We have studied a number of cooling methods, including the Dry lubrication, where lubricant is ambient air, spontaneous emission, induced emission. Doppler cooling with emulsion flood lubrication and molecular feed lubrication, the emissions were spontaneous and induced. Doppler cooling with MQL-molecular oil, here the emissions were the same as by the lubricants. We compare and analyse the results in our article. We tell the measurement parameters and our experiences.
