1. Introduction Hard turning is a machining process, which, increases productivity by eliminating unnecessary machining steps and improving the material removal rate [1]. Hard turning is used to machine difficult-to-cut materials like hardened steel (50–70 HRC) at high cutting speed with a singlepoint contact method. Cubic boron nitride (CBN), ceramics, and cermet are the commonly used tool materials [2]. Two varieties of CBN materials are commercially available: high CBN content (90%) and low CBN content (50%–70%) [3]. Hard turning has particular advantages when manufacturing engines, bearings, and precision components with levels of roughness as low as Ra (
