Analysis of Force Affecting in Turning Operation based on MRR

The present work performance of multi-layer coated tool in machining of hardened steel (AISI 4340 steel) under high speed turning. The influence of cutting parameters (speed, feed, and depth of cut) on cutting forces and surface finish has been analysed. Under the different cutting conditions, forces were measured using dynamometer. The results indicate that the depth of cut is the dominant factor affecting cutting force components. The depth of cut influences tangential cutting force more than radial and axial forces. The cutting speed affect stangential force more thanra dial and axial forces. Result can be predicted the parameter of cutting force to increase MRR by ANOVA method.
