An experimental study has been performed on AISI 4340 steel in this paper. The influence of approach angle, feed rate, cutting speedand depth of cut has been on cutting forces and tool tip temperature has been experimentally investigated. Before conducting experimentson the AISI 4340 steel work-piece, the chemical composition test, microstructure test were performed and hardness of the work-piecewas improved by heat treatment. A total of 64 experiments each by two different coated carbide inserts (PVD and CVD-coated) wereconducted on AISI-4340 steel under different environmental conditions (dry and MQL machining). During the experiments, approachangle, cutting speed, feed rate are varied to four levels and the depth of cut is kept constant to investigate the effect of the same on thethree cutting forces component and the temperature variations on the tool-tip. It is observed that the main cutting force was largest amongthe three cutting force components in case of AISI 4340 steel turning and MQL machining show beneficial effects compared to dry machining.

This investigation deals with machining AISI 52100 steel using a carbide-coated tool. The machining cutting force and tool tip temperature are measured online while turning using different cutting parameters. The surface roughness is also measured, but off-line after each cut. The obtained data are analyzed and the influence of the Cutting parameters on the machining variables is determined in the form of plots. Regression models obtained from the results are tested using additional experimental data.
