“…Thus, 3D topography characterization is eliciting extensive interest One of most important 3D topography characterization strategies is the ISO 25178 parameter standard introduced in 2007, and the increased attention was devoted to the effect of 3D roughness parameters on the tribological properties of contact interfaces. [15][16][17] For example, Tang et al 18 investigated the influence of typical roughness parameters on tribological properties under mixed lubrication and found that the surface with negative S sk and high S ku values is beneficial to friction reduction. Sedlaček et al 19 also demonstrated that S sk and S ku could regulate the frictional features of contact interfaces for further tribology design.…”

The characteristics of surface morphology markedly affect the tribological properties of contact interface such as lubrication and seal performance. In present work, the synergetic effect of surface connectivity and some three-dimensional topography parameters (ISO 25178) on the friction characteristics of a sliding contact interface, based on mathematical morphology and reciprocating linear tribotesting, is explored. The results indicate that the friction properties of sliding contact interface was significantly affected by the variation of surface connectivity. The increase in connectivity index would improve the relative contact area on the isotropic surfaces and affect the distribution and storage characteristics of the fluid, while this enhancement would be blocked on the anisotropic surface and the variation of connectivity index is obviously nonlinear with a shocking feature. The friction tests confirm that the friction coefficient of sliding contact interface decreases with the increasing surface connectivity index, which is mainly related to the enhancement of lubricant storage and flow in each void region and improving the lubrication behavior. Furthermore, the same variation law is applicable to the relationship between the functional morphology parameters and the friction property. The increasing Vvv and Sku, would contribute to a lower friction coefficient at the interface. Our work provides deep insights into regulating the tribological property of contact interfaces through surface topography control.

“…There are two important factors affecting the surface quality of the machined workpiece during the high-precision grinding: the abrasive grains (grinding tools) and the debris formation process. In a traditional grinding process, the machining dimension of the parts and the 3D model of the machined surface are obtained by instrument detection after grinding [1][2][3]. If the processing parameters are selected improperly, the parts will not meet the technical requirements, which will result in wasting money and resources [4].…”

A novel simulation approach for 3D surface topography that considers the elastic-plastic deformation of workpiece material during a high-precision grinding process is presented in this paper. First, according to the kinematics analysis for the abrasive grain during the grinding process, the motion trajectory of the abrasive grain can be calculated. Second, the kinematic interaction between the workpiece and the abrasive grains can be established, which integrates the elastic-plastic deformation effect on the workpiece material with the topography, the simulation results are more realistic, and the simulation precision is much higher. Finally, based on an improved surface applied to the grinding wheel, the surface topography of the workpiece is formed by continuously iterating overall motion trajectories from all active abrasive-grains in the process of high-precision grinding. Both the surface topography and the simulated roughness value of this work are found to agree well with those obtained in the experiment. Based on the novel simulation method in this paper, a brand-new approach to predict the quality of the grinding surface by providing machining parameters, selecting effective machining parameters, and further optimizing parameters for the actual plane grinding process, is provided.
