Abstract

This paper presents the comprehensive approach to the determination of the geometrical and functional characteristics of surface topographies generated on hardened steel parts of about 60 HRC hardness by high-precision cutting and abrasive operations. The initial surfaces were prepared by hard turning (HT) and then finished by precision hard turning (PHT), wheel (WG) and belt (BG) grinding operations. The three surfaces were finished to obtain the Sa roughness parameter of about 0.2 μm after HT and WG operations and 0.04 μm after BG operation. Surface roughness was characterized using the standard 2D and 3D roughness parameters and the fractal and motif parameters. Some important correlations between roughness parameters and surface functional properties are revealed. This study is a part of the research project devoted to the characterization of functional surfaces produced by cutting, abrasive and burnishing operations. The results obtained in the comparative study including hard turning, belt grinding and ball burnishing operations are presented in [1].
