The present work studies the 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 dep th of cut) on cutting forces and surface finish has been analyzed.L27 OA based Taguchi design was used to study cutting force (Fx, Fy and Fz) and surface finish (SR) of turning on AISI 4340 hardened steel work-piece. Cutting force and SR are mostly affected by speed and feed. Taguchi quality loss function was adopted to optimize the turning process with multiple performance characteristics.
