6 Temperature Measurement

1. Experimental Methods

Temperature measurement is most difficult in metal-cutting operations. As cutting edge is heated tool-workpiece interface temperature is very complex and hence it is difficult to develop a setup for measuring the temperature. Hence measurement of temperature with accuracy is still a big challenge [7].

We can use different types of equipment for measurement of the tool-chip interface temperature. Motorcu used an infrared thermometer (IR sensor) to measure the tool-workpiece interface temperature, a K-type thermocouple was used to measure tool temperature [4]. Nordgren A and Thakare A [8] used charge-coupled device (IR-CCD) technique. This imaging technique can be used for temperature measurement of 500–1000 °C, and with suitable calibration, good accuracy can be achieved. But the accuracy of the IR technique depends on the emissivity if both tool and workpiece.

Chinchanikar S et al. [9] investigated the tool-chip interface temperature while turning of AISI 4340 steel with two hardness values of 35 HRC and 45 HRC by CVD coated inserts. They develop a setup for temperature measurement based on tool-work thermocouple. This setup is shown in the Fig. 1.
