A Study of Recent Developments in Turning of Hardened Steel for Automotive and Industrial Applications.

Abstract

Hard turning is the widely used metal cutting process that reduces the workpiece diameter to create a smooth surface of the workpiece. This process with a wiper geometry tool has these advantages over the conventional machining process, which follows the grinding process later. The present study attempts to critically review investigations into forces coming and temperature raised during cutting, and surface roughness when cutting hardened steel. Previous studies have provided a lot of precious data. Still, some restrictions can be noted. To gain a thorough understanding of hard turning, the cutting characteristics of some different appropriate tool materials could be assessed. Further study is needed to focus on the properties encountered in hard cutting at higher cutting speeds. The tool nose radius is an important parameter in determining surface finish, but little research varies this parameter and the hardness and tool nose radius are combined to vary.
