“…Existing publications in the area of abrasive tool construction deal with interference with its design by making notches on the active surface [ 29 ], segmented construction [ 30 ], or discontinuities and modifications of porosity size [ 31 ]. Researchers have also analyzed the effect of grinding wheel texturing on the grinding process [ 32 ]. Texturing can also take place during dressing of the grinding wheel [ 33 ].…”

Finishing operations are one of the most challenging tasks during a manufacturing process, and are responsible for achieving dimensional accuracy of the manufactured parts and the desired surface topography properties. One of the most advanced finishing technologies is grinding. However, typical grinding processes have limitations in the acquired surface topography properties, especially in finishing difficult to cut materials such as Inconel 625. To overcome this limitation, a new type of grinding wheel is proposed. The tool is made up of grains of different sizes, which results in less damage to the work surface and an enhancement in the manufacturing process. In this article, the results of an experimental study of the surface grinding process of Inconel 625 with single-granular and multi-granular wheels are presented. The influence of various input parameters on the roughness parameter (Sa) and surface topography was investigated. Statistical models of the grinding process were developed based on our research. Studies showed that with an increase in the cutting speed, the surface roughness values of the machined samples decreased (Sa = 0.9 μm for a Vc of 33 m/s for a multigranular wheel). Observation of the grinding process showed an unfavorable effect of a low grinding wheel speed on the machined surface. For both conventional and multigranular wheels, the highest value for the Sa parameter was obtained for Vc = 13 m/s. Regarding the surface topography, the observed surfaces did not show defects over large areas in the cases of both wheels. However, a smaller portion of single traces of active abrasive grains was observed in the case of the multi-granular wheel, indicating that this tool performs better finishing operations.

“…Abrasive discs can be prepared from natural or synthetic materials, and they are usually prepared by attaching hard and abrasive materials to a binding matrix material. They are frequently produced from materials such as SiC, BC, BN, CeO, zirconia, aluminum oxide, iron oxide, silica and corundum [17][18][19][20][21][22]. However, today, studies on the preparation of abrasive discs from more sustainable, Apricot kernel shell is suitable filler for abrasive materials with its strong, hard structure and dense cellulose content.…”

“…cheaper and environmentally friendly materials are increasing. Within the scope of these studies, materials such as clay, cellulose fibers, talc, phenol-formaldehyde resin and rubber were tried in the preparation of abrasive discs [19][20][21][22][23]. However, today, studies on the development of optimum abrasive disc materials are increasing, depending on the purpose and place of use.…”

Apricot kernel shell is suitable filler for abrasive materials with its strong, hard structure and dense cellulose content. Therefore, within the scope of this study, polyester composite (PE-CAC) discs containing apricot kernel shell powder were prepared in order to prepare abrasive polyester composite discs. In order to prevent these discs from damaging the surface on which they are applied during use, different amounts of calcium carbonate were added into the structure. The chemical structure of the obtained composite discs was confirmed by Fourier transform infrared spectroscopy. Surface morphology and structure were confirmed by scanning electron microscopy technique. The distribution of additives within the composite structures was examined by EDX spectroscopy. The effect of heat generated during the etching process on the composite disc structure was investigated using thermal analysis techniques. The added composite structures were transformed into cylindrical discs with a diameter of 45 mm and a height of 30 mm and were used to remove paint on metallic surfaces. As the amount of apricot kernel shell powder in the composite structure increases, the abrasion efficiency increases. Additionally, as the PE/CaCO3 composite disc application time increased, a significant decrease in surface roughness was observed. Ideal surface roughness was achieved, especially after 10 seconds of application time. As a result, PE/CaCO3 composite discs with apricot kernel additives present an important alternative to existing methods, especially in the cleaning of dirt, rust and paint on metallic surfaces.

The dry fixed abrasive process integrates chemical reaction and ductile removal into one process and shows advantages against the conventional loose abrasive polishing in efficiency, geometric controllability, and waste disposal. However, it is worth noting that the wear and cutting temperatures encountered during the dry fixed abrasive process are areas that require further improvement. This manuscript develops textured polished wheels (TPWs) with three surface textures (spiral, linear, and radial) on the sintered polishing wheel. The influence of the TPWs on material removal depth and surface roughness for fused silica during the polishing process is investigated. The results indicate that the TPWs have the comparable material removal depth of the non-grooved polishing wheel while slightly increasing the surface roughness. However, it not only alleviates wheel wear but also improves the thermodynamics of airflow and chip removal in the polishing wheel and thus prevents surface wheel burning. Through experimental research, the TPW with a spiral-shape demonstrates the best performance with a material removal rate of 4.2657 µm/h and a surface roughness of approximately 3.0 nm.
