“…The material characteristics of the synthetic diamond differ from the metal matrix composites (MMC) 9 , 61 . The diamond grain wear occurs during the cutting of rock mainly due to abrasion caused by rock-forming minerals of granite and the cleavage fracture due to impact forces 6 , 36 . The wear of the metal matrix occurs due to abrasion and erosion 62 .…”

“…The smooth erosive wear is visible in the soft layer caused by the movement of slurry in a particular direction 62 . Meanwhile, the abrasion due to hard quartz-rich mineral particles is visible in the cutting layer in the form of cavities 6 . The wear track of abrasion-erosion is present in the direction of cutting.…”

This study is an attempt for comprehensive, combining experimental data with advanced analytical techniques and machine learning for a thorough understanding of the factors influencing the wear and cutting performance of multi-blade diamond disc cutters on granite blocks. A series of sawing experiments were performed to evaluate the wear and cutting performance of multi blade diamond disc cutters with varying diameters in the processing of large-sized granite blocks. The multi-layer diamond segments comprising the Iron (Fe) based metal matrix were brazed on the sawing blades. The segment’s wear was studied through micrographs and data obtained from the Field Emission Scanning Electron Microscopy (FESEM) and Energy Dispersive X-ray (EDS). Granite rock samples of nine varieties were tested in the laboratory to determine the quantitative rock parameters. The contribution of individual rock parameters and their combined effects on wear and cutting performance of multi blade saw were correlated using statistical machine learning methods. Moreover, predictive models were developed to estimate the wear and cutting rate based on the most significant rock properties. The point load strength index, uniaxial compressive strength, and deformability, Cerchar abrasivity index, and Cerchar hardness index were found to be the significant variables affecting the sawing performance.

“…The material is removed by diamond impact and grinding [26] during granite sawing. In this work, to explore the sawing mechanism and establish sawing force characteristics, the sawing geometry [25] is mathematically analyzed based on the segment morphology and workpiece motion. The undeformed chip geometry can be further derived, such as contact arc length and maximum undeformed chip thickness.…”

Sawing by circular saw blades is predominant in the mechanized treatment of natural stone. The predictive sawing force is crucial for optimizing, controlling, and monitoring the sawing process. In this work, a novel model for predicting sawing force, which is based on the distribution of the undeformed chip thickness at the sawing contact arc, was proposed. Based on the analysis of the chip geometry of the circular saw blade, the segment surface was divided into the front end and rear end according to the contact pattern between the segment and granite, and the models of the maximum undeformed chip thickness of diamond particles on the front end and rear end were established. Results suggest that the new proposed force model fully considered the distribution of undeformed chips compared with the current model. And the novel model has higher prediction accuracy, the mean maximum absolute error rate was within 3.77%, and the maximum absolute error rate was within 7.83%. Through theoretical analysis, the ratio (is 1.67) of the maximum thickness of the undeformed chips of the front segment and rear segment can fully explain the wear nonuniformity of the segment. The proposed model is of great signi cance to the optimization of saw blade structure and process parameters.
