Abstract

Hard turned materials are widely used in manufacturing industries. However during hard turning high heat is generated at the cutting zone, that causes the earlier tool wear, which tends to decrease the machining performance. The heat generation during hard turning can be controlled by using cutting fluids during the machining. Therefore an attempt has been made in this research work to optimize the process parameters during hard turning of AISI 4340 steel with CBN (Cubic Boron Nitride) inserts under wet condition of machining. The cutting speed, feed rate, workpiece hardness, and tool nose radius were selected as process parameters. The cutting force and chip-tool interface temperature were chosen as performance parameters. The central composite design was selected to perform the experiments. The analysis of variance (ANOVA) was carried out to analyze the significance of the process parameters. The second order mathematical models for cutting force and chip-tool interface temperature were prepared. The optimal values of the process parameters which provide minimum values of cutting force and chip-tool interface temperature are suggested.
