“…Therefore, quantification of all the features associated with the ceramic grains becomes useful to understand the correlation between the microstructural assemblage and mechanical characteristics of the composite and the wear mechanisms of the tool material. Nowadays, surface topography design of abrasive tools is becoming a frontier concept to improve the tool performance [8]. For instance, innovative manufacturing of honing stones has been approached by using glue and piezoelectric nozzle, as well as regular deposition with defined patterns of the ceramic grains on the tool surface [9].…”

Non-conventional super hard abrasive tools are made of composite materials containing super hard grains, e.g., diamond or cubic boron nitride (CBN) grains, bound by a metallic constitutive phase. These tools are usually produced by means of sintering, and are widely applied in the abrasive machining processes of modern manufacturing, especially in precision machining. The abrasive grains, which induce the material removal processes, are embedded in the metallic binder. They emerge as a consequence of self-dressing, resulting in a self-sharping effect. Therefore, the cutting surface of the tool displays an irregular topography. Quantification of surface topography scenario may supply valuable information to evaluate and understand its correlation to wear mechanisms. In this study, an experimental protocol consisting of five steps: specimen preparation, surface scanning, image assembly, image digital processing and surface quantification, is proposed and validated by characterizing two CBN honing tools used for precision machining: B151/L2/10/50 (B151) and B91/128/x44/35 (B91) CBN honing stones. It involves the use of laser scanning microscopy and digital imaging processing for assessing significant dimensional, geometrical and positional properties of CBN grains at the surface of super hard abrasive tools. It is shown that surface topography quantification is an effective method to evaluate and obtain the defined parameters. However, smaller grains may require images with higher resolution; and thus, scanning must be refined. Finally, a critical comparative analysis of the experimental results attained for the studied tools points out honing stone B91 as more appropriated than B151 one for achieving a higher machining quality of the workpiece.

Surface structural texture is designed to achieve specific functional performance for many advanced applications. After a brief review of current manufacturing methods for textural surface, this paper focuses on the study of microstructural surface creation by grinding. The axial and peripheral cross-sections of textured wheels under different dressing overlap ratios U d are illustrated. A set of microstructural texturing models are proposed and the influences of dressing and grinding parameters are discussed. The texture formation is analysed in considering each cutting point in grinding kinematic movement. A significant effect of the grinding contact length on the texture formation is noticed, which defines a texture pattern limitation for grinding to manipulate. Typical surface texture characteristics are introduced to assess the structural surface features and the corresponding theoretical models are validated by experimental results. The relationships between the textural gouge size and the kinematic conditions of dressing and grinding have been delineated for the guidance of grinding texturing strategy. The component waviness on textured components clearly shows the importance of rotational ratio on the layout of microstructural texture. The paper lays down an important foundation for surface microstructural texturing by grinding.

“…Such technical development can not only widen the application range of LST but also open windows for creative surface topography design. An example of successful application of this approach is found on enhanced abrasive ability and/or lubrication efficiency of grinding wheels by means of manufactured surface topography, in terms of either micro-texturing or defined ceramic grain patterns [22][23][24].…”

Abrasive effectiveness of composite-like honing stones is related to the intrinsic surface topography resulting from the cubic boron nitride (CBN) grains protruding out of the metallic matrix. Within this framework, Laser Surface Texturing (LST) is implemented for replicating topographic features of a honing stone in a WC-base cemented carbide grade, commonly employed for making tools. In doing so, regular arrays of hexagonal pyramids (similar to CBN grains) are sculpted by a laser micromachining system. Micrometric precision is attained and surface integrity does not get affected by such surface modification. Finally, potential of laser-patterned cemented carbide tools, as alternative to conventional honing stones, is supported by successful material removal and enhanced surface smoothness of a steel workpiece in the abrasive testing.
