“…The average chipping thickness increases with the feed speed, and increases as the rotating speed decreases. According to previous studies [1,[3][4][5][6] that the cutting forces increase with the average chipping thickness. Therefore, the cutting forces are increasing as the feed speed becomes higher, which leads to the wear of diamond segments.…”

“…The result indicated that the depth of cut has the prominent effect on the sawing forces. The predictive model of sawing power was proposed by Huang et al [6], which experimentally validated and modified based on the tangential force in the diamond circular saw. It provided the basis for optimizing sawing parameters and reducing energy consumption.…”

A great quantity of granite sawing experiments was carried out to explore the cutting performance offrame sawing machine with the horizontal reciprocating cutting mode.A model of average thickness of cutting chip was established, and characteristics of cutting forces were analyzed. The mechanism of wear was revealed by analyzing the width of the saw kerf and the wear morphology of the diamond segments. The results showed that the wear resistance and the cutting forces ncrease as the feed speed. The cutting forces change abruptly at the reversing point during granite cutting. At the same time, the proportion of macro-fractured and pulled-out particles and the mean wear rate of segments increase with the feed speed, and the mean protrusion height of the grits is less than 100 μm. The width of the saw kerf is gradually reduced as the sawing progresses, forming an inverted cone with a large upper side and a small lower side. Besides, the studies found that the wear of the segments remains consistent in two directions. The prominent phenomenon of the diamond particles on the side surface is more obvious as the feed speed increases.The research can provide certain data support for granite cutting, and lay the foundation for the subsequent optimization of the structure and equipment.

In this paper, a characterisation of diamond abrasive grains of grinding tools using industrial X-ray computed tomography (XCT) is carried out. One of the most challenge tasks in the characterisation is extracting the diamond abrasive grains from the XCT volume data. Methods that are able to extract the grains are then developed and introduced in this paper. The first step is to create a triangular mesh surface from the reconstructed volume file using a gradient anisotropic diffusion filter. The second step is to convert the measured greyscale volume into a signed distance field using a global threshold value and then a localised method for grain segmentation. To validate the proposed method, three different types of grinding tool specimens are measured and analysed. Each abrasive grain is segmented and the distributions of grains (with both random and designed patterns) are then calculated, plotted and analysed. The quantitative analysis clearly shows the deviations between the measured distribution and the designed pattern of the grinding tool, which indicates that the proposed method can provide an accurate and comprehensive characterisation of the grinding tools.

Circular saw blades are widely used in stone processing. The circular saw blade cutting hard rock numerical simulation model based on ANSYS/LS-DYNA was established to investigate the complex dynamic problem in rock cutting. The failure mechanism of the rock and the influence of cutting parameters on the cutting force and rock fragments were studied by numerical simulation. The results demonstrated that the failure modes of the rock were mainly tensile failure with some shear failure and compressive failure. The cutting force and the number of fragments increased with the feed speed. With the increasing circular saw blade rotational speed, the cutting force and the number of fragments decreased and tended to stabilize. With the distance between the circular saw blades increasing, the cutting force and rock fragments number increase and then maintain basic stability, and when the distance between double circular saw blades reaches 25 mm, it will form a completed rock plate and the interaction of circular saw blades will decrease. The numerical simulation can accurately simulate rock breakage and force when a circular saw blade cuts rock.
