A Technological Review on Temperature Measurement Techniques in Various Machining Processes

The cutting temperature and the amount of heat produced at the tool–chip interface during different machining operations have been recognized as main factors that influence the cost of machining as well as the cutting tool performance in terms of surface finish and the production time involved while machining. Cutting tool efficiency is largely affected by temperature generated while machining which limits the quality of the finished product. This paper presents a review of various methods for the measurement of tool and workpiece temperature distribution in different machining processes. Different temperature-sensing techniques are discussed along with their limitations. A comparison between several sensing methods has been done in terms of cost-benefit, accuracy, ease in measurement and response time in order to find out the best-suited method.
