Hard turning offers improved manufacturing efficiency but requires great control of the cutting process to achieve required machining-induced surface integrity with respect residual stresses, topography, and near-surface microstructure. This research work is focused on studying effect speed, feed rate, depth cut, chamfer angle, coolant pressure after hard martensitic AISI 52100 steel. The resul...

Hard turning, i.e., turning hardened steels, may produce the unique “hook” shaped residual stress (RS) profile characterized by surface compressive RS and subsurface maximum compressive RS. However, the formation mechanism of the unique RS profile is not yet known. In this study, a novel hybrid finite element modeling approach based on thermal-mechanical coupling and internal state variable pla...

Abstract The effectiveness of antiwear additives in laboratory tests is commonly evaluated using specimens made AISI 52100 through-hardened bearing steel. However, many lubricated machine components are steels with significantly different material compositions, which raises an important practical question whether the performance these other steel types from that established 52100. To help answe...

In this paper, 3-D Finite Element Method (FEM) based numerical modelling of precision hard turning has been studied to investigate the effects of chamfered edge geometry on tool forces, temperatures and stresses in machining of AISI 52100 steel using low-grade polycrystalline cubic boron nitrite (PCBN) inserts. An Arbitrary Lagrangian Eulerian (ALE) based numerical modelling is employed for 3-D...
