“…Zhang et al 15 compared wear mechanisms of diamond segments in a traditional frame saw and an eccentric frame saw, confirmed that tails formed behind diamond particles on the segment can provide a stronger holding strength. Similarly, extensive studies have been conducted on related area like wear characteristics of the cutting tool, [16][17][18][19][20] sawability, 21,22 and sawing performance. 23,24 Existed literatures have proved the complexity of wear mechanism of diamond tools.…”

Carbon fiber reinforced cement-based composite material (CFRC) is a novel type of composite material that involves the incorporation of carbon fibers into ordinary concrete. This addition effectively enhances the tensile strength, deformation performance, and dynamic load resistance of reinforced concrete structures. Consequently, CFRC has found increasing applications in the construction industry. The objective of this research is to investigate the wear mechanisms of diamond tools during the sawing process of CFRC and offer guidance on cost reduction through the optimization of processing parameters. The wear analysis of diamond segments can be divided into two categories: matrix wear and diamond particle wear. The diamond particles can exist in different states, and the formation of voids resulting from the detachment of diamond particles is considered as a reference point. The analysis reveals that abrasive wear is the main mechanisms of matrix wear in CFRC sawing. The wear resistance is strongly influenced by the proportion of diamond particles in favorable states, which is determined by the applied loads and operating parameters. The proportion of diamond particles exhibits a clear variation with adjustments made to the feeding speed. Notably, an increase in feeding rate results in a significant decrease in the percentage of blunt particles, reducing it from 28% to 6%. To achieve a lower wear rate, a predictive model was established using Design Expert software based on the experimental results. The model demonstrated that a wear rate as low as 268.5 mm/m2 can be achieved with a flywheel speed of 78 r/min and a feeding speed of 90 mm/h. The optimization process, aimed at minimizing wear rate, was successfully carried out without compromising productivity.

“…Te diamond circular saw blade is widely used in cutting and processing natural stones, which is an important industrial processing tool. Te mechanical processing mechanism of rock difers from that of metal materials, and the stone cutting process is more sophisticated owing to the impact of the rock's brittleness [1]. Te rock cutting process involves a wealth of the cutting mechanism, including rock fragmentation, crack generation, and material removal mechanism, as well as the nonlinear vibration response of the saw blade, stress distribution, dynamic cutting force, and the wear state of saw segments.…”

A simulation approach was utilized to investigate the mechanics of cutting rock using the diamond circular saw blade in this paper. The smoothed particle Galerkin (SPG) method was used to numerically simulate three factors, including the dynamic mechanical behavior of the circular saw blade, the damage law of the circular saw blade, and the cutting force of the saw blade. The experimental comparison indicated that the SPG approach is feasible and accurate in the analysis and simulation of the rock cutting mechanism. The rock cutting is a process of material cyclic removal. The wear parts of the saw blade are most obviously manifested at the end of the saw segments. The water groove is also readily damaged in the alternating action, which has a significant impact on the service life of the saw blade. The effects of speed, cutting depth, and feed speed on the cutting force are discussed. The results reveal that these mentioned factors are important to the quality of rock cutting.
