Performance Evaluation of Ti(C,N) Based Cermet Inserts for Dry Turning of SAE 1018

Abstract

Selection of cutting tools stands as a marvel of ultimate significance for machinists and manufacturing personnel which hamper the quality of surface, machining time and energy requirement. Cermet insert is a key preference for particular dry machining finishing operation in many industries. It possesses characteristic like high-temperature hardness, wear resistance, plastic deformation resistance, high chemical stability, and welding resistance. On the other hand, it is a moderate value of fracture resistance, thermal crack susceptibility, and shock resistance. The uncoated cermet insert has the capacity to the machining of the workpiece having hardness range between 35 to 40 HRC. In this research paper, the performance of Ti(C, N) based cermet insert is evaluated for the machining of low carbon steel (SAE 1018) with no coolant supply (dry turning condition). The Material removal rate (MRR) and surface finish of the component has been evaluated for cutting speed, feed and machining time. Depth of cut is considered as constant for the experimentation.
