“…Another approach to wheel surface generation is given in [2,26,27] -according to it, objects that represent abrasive grains are first created, and then these objects are placed in space, which gives a comprehensive description of the grinding wheel's active surface (A1) .…”

Title of article: "Metodyka modelowania powierzchni czynnej ściernic" ("Methods for modeling the active surface of grinding wheels") Mechanik, Vol. 91, No. 10 (2018): pages 907-914 In this paper many different methods of generating the topography of the grinding wheel surface and the methodology for assessing the compatibility of models with the surface of real tools was presented. The methodology was indicated that certain features regarding the shape and position of the highest vertices are decisive for assessing the model's conformity with the real surface of the grinding wheel . The significance of not only the form of the distribution of the vertices of the grains was emphasized, but also the significance of the fragment of the probability density function relating to the highest vertices and the autocorrelation of the vertex position as the most important feature, which often are overlooked in the models described in the literature. KEYWORDS: The grinding wheels active surface, grinding wheel model, verification of the grinding wheel model.

“…The results remark the importance of surface topography and dressing conditions on the contact area, as well as wheel deflection. In Wang et al [27], a simulation method was proposed to visualize the grinding surface topography and predict grinding surface roughness. It was shown that at small cutting depth the surface microstructure could be improved up to a certain value of the ratio between the cutting velocity and feed rate.…”

Grinding is one of the essential manufacturing processes for producing brittle or hard materials-based precision parts (e.g., optical lenses). In grinding, a grinding wheel removes the desired amount of material by passing the same area on the workpiece surface multiple times. How the topography of a workpiece surface evolves with these passes is thus an important research issue, which has not yet been addressed elaborately. The present paper tackles this issue from both the theoretical and the experimental points of view. In particular, this paper presents the results of experimental and theoretical investigations on the multi-pass surface grinding operations where the workpiece surface is made of glass and the grinding wheel consists of cBN abrasive grains. Both investigations confirm that a great deal of stochasticity is involved in the grinding mechanism, and the complexity of the workpiece surface gradually increases along with the number of passes.

“…The spherical shape is the most widely used as an abrasive grain model [17][18][19][20]. Other simple geometries such as hexahedron and octahedron are often used as simplified models of abrasive grain [21][22][23]. However, there are little analyses in the relevant literature on the simplified model modeling method and their cutting mechanism for truncated cone shape abrasive grain.…”

Based on the random distribution characteristic of abrasive grains for the grinding wheel circumference surface during the manufacturing process, considering the grinding parameters and deflection parameters comprehensively, a randomly deflected truncated cone shape single abrasive grain cutting simulation model was established. Then, studying its cutting mechanism: the trajectory length value by numerical method and formula method were compared, the consequence indicates that the error is extremely small, this demonstrates the accuracy of the numerical method. The calculation and analysis of the workpiece cutting surface topography and the undeformed chip shape were carried out, it shows that the cutting surface topography and the undeformed chip shape are coincident. The influence laws of each grinding process parameter on the material removal volume (MRV) and material removal rate (MRR) were investigated, the results display that the grinding method affects the changing pattern of MRV and MRR, when the grinding method was up-grinding, a high wheel speed or a small wheel diameter are able to enhance the MRR, the MRV and MRR are increments with the increasing workpiece feed speed or abrasive grain cutting depth, and the MRV and MRR decrease with the raising of the absolute value of single abrasive grain deflection angle. The situation is a similar or opposite trend in down grinding. This work can provide a theoretical reference for the selection and optimization of grinding parameters, and further lay a foundation for the research in the grinding mechanism of the grinding wheel.
