Analysis and Prediction of feed force, tangential force, surface roughness and flank wear in Turning with uncoated carbide cutting tool using both Taguchi and Grey based taguchi method

The aim of the present study is to investigate the effects of process parameters (cutting speed, feed rate and depth of cut) on performance characteristics (tangential force, feed force, surface roughness and flank wear ) in turning of EN-19 steel with uncoated carbide cutting tool. Experiments are designed and conducted based on Taguchi's L27 orthogonal array carried out under dry cutting conditions for tangential force, feed force and surface roughness, whereas for the flank wear the experiments are conducted as per L9 orthogonal array. The responses are feed force, tangential force, surface roughness and flank wear were recorded for each experiment The depth of cut was identified as the most influential process parameters in the responses of both tangential force and feed force. The feed rate was identified as the most influential process parameter on the surface roughness, while the cutting speed has a significant contribution for flank wear. Grey relational analysis is used to optimize the multi-performance characteristics to minimize the tangential force and surface roughness. The feed rate was identified as the most influential process parameter in the responses of both tangential force and surface roughness
