Abstracts: In metal cutting, the heat generated on the cutting tool is very significant for the performance of the tool and quality of the work piece. Maximum heat is generated on the tool - chip interface at some point during machining. The machining can be superior by the knowledge of cutting temperature on the tool. In this study, the temperature generated on the cutting tool and experimental methods for the measurement of temperatures are review. Special focus has been paid to tool- work thermocouple method and an experimental setup made-up to measure the temperature on the cutting tool and work piece junction during metal cutting is described. With this method, the middling temperature at the tool-chip interface is measured. The output of the thermocouple is in the mill-volt range and measured by a digital milli-voltmeter .The voltmeter is essentially current sensitive device; hence the meter reading will be reliant on the electromagnetic force generated by tool-work thermocouple. The thermoelectric power of the circuit is usually tiny and estimated by calibrating the circuit next to a reference thermocouple (Alumel Cromel K type).
