A Study of Experimental Temperature Measuring Techniques used in Metal Cutting

Abstract

From the beginning of machining of materials, rise in tool, chip, and work piece temperature remains a problem for engineers. The excessive rise in temperature severely affects the tool life and the quality of the work piece. To check this issue, engineers and scientists are tirelessly investing their efforts. Measurement of the tool, chip, and work piece temperatures takes a vital breakthrough in this direction. Several methods are developed and tested from time to time. But none is found perfect, some are better at a certain situation but fails at another. The appropriate technique for a given problem depends on the situation under consideration, such as the ease of accessibility, situation dynamics, desired accuracy, spot size, and economics. These techniques are broadly categorized in three categories, namely analytical, experimental, and finite element methods. Experimental is more practical, and more accurate among these three anchors. In this paper, all experimental techniques for the measurement of tool, chip, and work piece temperatures distribution are studied in depth and presented in a user friendly concise manner.
