Machining of steel inherently generates high cutting temperature, which not only reduces tool life but also impairs the product quality. Further, the lubricant effect deteriorate the working environment and lead to general environmental pollution. In this work, the cutting tool used is uncoated carbide insert with st37 steel as workpiece material to measure the temperature of the tool-chip interface in dry turning. Two different approaches are implemented for temperature measuring: an embedded thermocouple into the cutting tool and infrared camera. Comparisons are made between experimental and FE results. The influence of cutting speed, feed rate and depth of cut on the temperature are investigated. Afterwards, an expression for the effects of cutting conditions on tool temperature are determined using a design of experiment developed by factorial regression method. With the aid of experimental results is concluded that the main factors of the increasing cutting temperature are, cutting speed, feed rate and depth of cut respectively, It is also determined that interaction between cutting speed and feed rate has maximum effect on increasing in cutting temperature.
