Experimental Investigation of Tool Wear Behavior of Multi-Layered Coated Carbide Inserts Using Various Sensors in Hard Turning Process

Tool wear analysis became a vital area of research in the current scenario of mass machining or mass production in industries especially in the event of machining of hard materials. The applications where hard steel replaces the less hard materials, multi-layered coated carbide inserts have shown better results in comparison with single-layered coated carbide inserts. Different sensors like cutting force sensor, roughness sensor, temperature sensors, etc. can be used to associate its particular output with tool wear. In this paper, a study has been carried out to report the tool wear behavior of multi-layered coated carbide inserts while machining hard steel of 55 HRC in dry cutting conditions. Different sensors have been used during experimentation and their outputs have been analyzed to investigate the behavior of cutting tool in real life situation for precision machining.
