Nowadays, hard turning is frequently used to replace grinding. The economic benefits of hard turning are obvious but for achievable accuracy the situation is somewhat ambiguous. Although machine tool factories offer lathes with the same accuracy as grinding machines in some cases problems may arise in keeping the prescribed geometrical accuracy ...

State of the Art in Hard Turning
International Journal of Machine Tools and Manufacture, 2012Abstract Hard turning is gaining grounds for machining hardened steels as it has several benefits over grinding. There are several issues, which should be understood and dealt with, to achieve successful performance of the process. Researchers have worked upon several aspects related to hard turning.

Machined Surface Temperature in Hard Turning
International Journal of Machine Tools and Manufacture, 2017Abstract Machined surface temperature is critical in turning of hardened steels because high surface temperature can lead to the formation of the white layer, which may have negative impacts on the steel fatigue life. This paper presents two experimental methods to measure machined surface temperatures in hard turning.

Hard turning is a turning operation performed on hard materials (hardness more than 45 HRC) in order to reach surface roughness close to that obtained in grinding. The development of this technology was accompanied by the development of new cutting materials such as cutting ceramics, cubic boron nitride and polycrystalline diamond.

Journal of Superhard Materials, 2009
The results of the comprehensive studies of a highly efficient method of finishing, the so-called hard “skiving” turning, are discussed. Special features of the oblique cutting with a tool equipped with cBN-based polycrystalline superhard materials are shown, the regularities of the surface roughness formation and surface layer hardening in machining ...

Comparison of rotational turning and hard turning regarding surface generation
Production Engineering, 2014In this paper, two different turning processes namely rotational turning and hard turning are compared to each other regarding surface generation aspects. By experiments it is shown that, with higher feed rates, rotational turning yields same surface quality as hard turning.
