In recent years, hard turning has emerged as a burgeoning cutting technology for producing high-quality finishing of cylindrical-shaped hardened steel variety industrial applications. Hard under dry was not accepted because the generation higher temperatures which accelerated tool wear and produced an inferior surface finish. Nowadays, minimum quantity lubrication (MQL) is widely in to reduce p...

Abstract This paper concerns the tool wear in hard turning of AISI 52100 hardened steel by means PCBN tools. The purposes this work are development a model and its implementation FEM-based procedure for predicting crater flank progression during machining operations studying influence on process terms geometry modifications stress variation tool. developed model, able to update worn as function...
