Hard machining, as attractive replacement for many rough and finish grinding operation, generates high cutting forces and temperature that enhance tool wear when act together. Therefore, the tool geometry and machining parameters have to be carefully optimized for a given material. Because of high cost and time consuming experimental work up-to-date advanced software for modeling and simulation brings quick and adequate solution. The aim of this contribution is to study the influence of cutting parameters and material hardness on accompanying phenomena when hard turning process with mixed oxide ceramic inserts. Hardened steel with different hardness level of HRC 46, HRC 55 and HRC 60, respectively, has been employed in modeling and trials. In order to better understand dynamics of cutting hardened steel, investigation has been performed making use finite element simulation in two dimension, and experimental analysis of cutting force. The potentiality of the model as well as the experimental results are compared and discussed.
