“…It has already been shown in previous research works by the authors that the grinding of the two tested granites produces both fine particles (PM2.5) and ultrafine particles (diameters lower than 100 nm) [ 3 , 5 , 8 , 10 , 16 ]. Theses previous research works were done using rotatory grinding with exception of the work by Kouam et al [ 10 ] which focused on ban polishing.…”

“…Some investigations have been carried out on the emission of fine and ultrafine particles as well as on part quality during the surface polishing of this material. It was found in the literature that, increasing the spindle speed resulted in high generation and dispersion of microparticles, with high concentrations located far from the particle generating zone [ 8 ], whereas such emissions are decreased by high feed rates [ 9 ]. Kouam et al [ 10 ] found that during granite polishing, the emission of fine and ultrafine particles and the quality parts are highly influenced by the concentration of quartz in granite and the cutting conditions.…”

CNC Edge Finishing of Granite: Effect of Machining Conditions on Part Quality, Cutting Forces, and Particle Emissions

Edge finishing is a shaping process that is extremely important in the granite and marble processing industries. It does not only shape the edge but also makes it shiny and durable. However, this process generates dust (fine and ultrafine particles) that can have a significant impact on air quality in the workshop and can put workers’ health at risk. While environmental requirements and occupational health and safety regulations are becoming increasingly stringent, at the same time, industries must continue to produce quality parts at competitive prices. The purpose of this study was to examine the surface quality, the cutting forces, and the emission of fine (FP) and ultrafine (UFP) particles during wet and dry edge finishing of granite edges as a function of the machining parameters and abrasive grit sizes. Three machining operations were investigated: roughing, semi-finishing, and finishing, using diamond abrasives (with grit sizes 45, 150, 300, 600, 1500, and 3000). The experiments were carried out on two granites, one being black and the other white. The tested spindle speeds ranged from 1500 rpm to 3500 rpm and the feed rates from 500–1500 mm/min. It was found that roughing operations produce more fine particles while finishing operations produce more ultrafine particles. These particle emissions, as well as the part quality and the cutting forces are strongly dependent on cutting speed and on the grit size of the abrasive used.

The role of the application of various natural stone materials in the mechanical engineering and construction industries has steadily increased for the past few years. After the Fourth Industrial Revolution, the programmed CNC machines also came to the fore in the case of machining granites. Due to the development of machine tools, the surface quality of granites increased. As the granite has a heterogeneous grain structure, it is not possible to follow the formulas used in the machining of metals. We need to study the effects of the granite forming minerals on the surface roughness in order to achieve the surface quality determined by customer's needs. The research published in this article examines the surface damage of minerals in granite caused by the milling process. As a result of the research, we obtained an accurate picture of the effect of each mineral type on surface roughness and we were able to analyze the extent of the effect caused by each mineral on the surface. We are given a steady basis by the experiments presented in this article to design adequate surface quality and to develop a pre-estimation system.

Milling of granite surface is getting increasingly important in the industry. A major problem is that the effect of granite minerals on surface roughness is currently unknown. The research in this article aims to examine these effects. During the experiment, six surfaces with different cutting speeds were examined on the surface of three different granite samples. The color of the various minerals was determined by light microscopy, and a scanning electron microscope (SEM) and X-ray diffractometer (XRD) were used to analyze the composition of the samples, and a confocal microscope was used to measure the surface roughness of each mineral. From the results of the investigations, we deduced different correlations between the minerals forming granite and the surface roughness. Area-based surface roughness was used in this study because it results more accurate data. From the results, we conclude that the roughness of different surface-forming minerals varies greatly. This causes a high average surface roughness value.
