Abstract
In precision hard turning, the machining performance is highly influenced by the frictional heat generated during the process. The high frictional heat generation causes the earlier tool wear, which tends to decrease the machining performance. The coating of hard materials on cutting tools is applied to enhance machining performance. In this research work, the performance of TiN-coated CBN tools was evaluated during hard turning. The workpiece hardness, tool nose radius, cutting speed and feed rate were selected as process parameters. The cutting force and chip–tool interface temperature were chosen as performance parameters. Center composite design was chosen for experimental design, and analysis of variance (ANOVA) was performed to analyze the significance of the process parameters. The outcomes are compared with uncoated CBN tools. The results showed that the machining performance of TiN-coated CBN tools was superior in all cutting conditions.
