Experimental and Numerical Investigation of Temperature Distribution in the Cutting Zone with Different Coated Tools in Orthogonal Turning Operations

In orthogonal turning operations, the mechanical energy is converted into heat. The generated heat influences tool life and wear, and the accuracy and quality of workpieces. In the current work, the temperature distribution at cutting zone was studied experimentally and numerically. The K-type thermocouple was utilized to measure the cutting zone temperature during turning process for steel AISI 1010. DEFORM-2D has been utilized to simulate the turning operation, which was carried out using many coated and uncoated carbide tools. The experimental tests were implemented at constant depth of cut with different feed rates and cutting speeds. The results of numerical and experimental tests are illustrated. The influences of coated and uncoated tools, feed rate and cutting speed in temperature distribution at cutting zone are discussed, whereby the TiN/Al2O3/TiCN coated tool has the lowest temperature distribution at cutting zone compared to the other coated and uncoated tools, while the uncoated tool has the highest temperature distribution compared to coated cutting tools. Also, the increasing of cutting speed and feed rate led to an increase of temperature at the cutting zone.
