“…These have various effect on the machined surface, like the alteration of the stress state belove the surface. In abrasive machining a factor, which affects the stresses and localization area is the grain concentration [5]. However, Yang et al also showed, that if the grain size increased, the surface roughness greatly changed [6].…”

Honing is a wide-spread applied machining procedure in finish manufacturing of high precision bores (for example surfaces in internal combustion engines). Machining procedures can be analysed from the point of view of the energy efficiency, productivity, surface quality, etc. In this paper the achievable surface quality after the honing process is studied on sleeves with EN-GJL-250 lamellar cast iron alloy material. The cutting experiments were planned according to the 23 full factorial design of experiments method. Two levels of the analysed factors were chosen in this study. The pressure on the honing stone, the feed of the tool and the average grain size are changed, which resulted in 8 experimental setups. After the roughness measurement and profile evaluation, the main effects are analysed of these 3 parameters. Equations were determined according to the principle of the design of experiment method. The effect of the studied machining parameters is analysed by the application of these equations. The findings in this paper make it possible to explain some phenomenon in the honing process and allow the planning of future experiments in this topic. It was found that lower pressure, higher feed, and finer grains are favourable to achieve low roughness values.

“…It significantly affects the material removal rate [5] and the surface roughness as well [6]. The concentration of the abrasive particles also affects the machined surface, such as the stress distribution [7]. Abrasive processes also have a "self-sharpening" effect, as the worn particles breaks out from the tool due to the increasing cutting forces, revealing new, sharper grains to the cutting zone [8].…”

In the examination of the finishing procedures, it is also necessary to examine the parameters characterizing the functionality in addition to the numerical values of the surface roughness. This allows us to get a more complex picture of the behaviour of the machined surface during the working conditions. In this paper, the parameters of average roughness, surface skewness, and surface kurtosis are examined for holes machined with honing. During the experiments, the full factorial experimental design is used. Thus, the cutting experiments were performed with a total of 8 settings for 2 values of three selected parameters (average grain size, pressure, feed rate). The effect of the investigated technological parameters on the analysed roughness parameters was given in the study.

This research study addresses the issues with additive manufacturing of high abrasive concentration as well as highly affordable resin-bond grinding wheels. High-concentration resin bond grinding wheels are high-demand cutting tools that provide high-efficiency grinding operation for a broad range of ferrous and nonferrous metals. Adding a high concentration of abrasive grains into the blend while using high-temperature acrylic resins as a bond material has encountered some difficulties during digital light processing (DLP), such as insufficient flow of material resulting from the high inherent viscosity of the pure resin and less printability due to their dark color, which become worse by adding a high volume of abrasive grains. An engineered bond material achieved through the mechanical alloying of acrylate photopolymers with tailored properties has been discovered during this research study, taking advantage of reduced price, excellent grinding performance, and high grain concentration. The experimental grinding operations comprising medium and high material removal rates were carried out to prove the supreme properties of the SiC- and diamond-printed grinding wheels toward having high accuracy besides a high-quality finished surface. Mechanical characterization including tensile test and grinding performance examination comprising tool wear, cutting force, surface quality, and surface integrity were conducted on the printed and ground parts. The results showed that integrating 14.6 Wt% of Resin A (with higher thermal resistance and viscosity) into the wheel’s composition could contribute to the fabrication of a high-performance grinding wheel, besides having a reliable, fast, and feasible printing process. Furthermore, On-machine and out-of-machine measurements on the ground surface signified that the composition with the highest Resin B concentration (GW-H) offered up to 2 times higher mechanical properties, 33–50% lower grinding forces, 25–50% improved surface qualities, 2–3 times extended tool life span, and less interval dressing operation compared to the grinding wheel containing the lowest Resin B concentration (GW-L).
