Summary: The study proposed a brazed diamond grinding wheel with defined grain distribution to improve the machining performance, showing that under similar operating conditions, the brazed grinding wheel generated smaller grinding force, smoother ground surface, and lower surface roughness compared to the electroplated grinding wheel. Additionally, the ultrasonic assisted grinding reduced grinding force, force ratio, surface roughness, and profile wave height compared to conventional grinding, but also caused a more extensive ultrasonic vibration effect on grinding.

Summary: This paper investigates the dry grinding characteristics of SiCp/Al composites with different micro-textures on monolayer brazed diamond grinding wheels. The results show that the micro-textures on diamond grits induce cleavages and form more micro-cutting edges during the grinding of SiCp/Al. The wheel with micro-grooves and micro-holes exhibits the lowest grinding force, grinding temperature, and surface integrity. It also produces smaller grinding chips and reduces the fracture, crushing, and pull-out of SiC particles on the ground surface of SiCp/Al composites compared to other wheels.

Summary: The study reveals that the relationship between ground surface roughness and theoretical undeformed chip thickness is significantly affected by the grinding wheel wear state. A linear relationship was found among normal grinding force, undeformed chip thickness, and ground surface roughness by introducing the normal grinding force. Sensitivity analysis was conducted to guide the parameter adjustment to maintain the stability of ground surface roughness.

Summary: This study explores the feasibility of high efficiency and precision grinding of brittle ceramics. Experimental grinding tests were conducted on SiC ceramics using monolayer brazed diamond wheels. The results show that the maximum undeformed chip thickness and grinding wheel speed significantly affect the material removal and subsurface damage of the ground surface, while the grinding depth has a minor influence.

Summary: Diamond, with its excellent properties, shows great potential as a substrate material for sensors and semiconductor devices. However, its high hardness and chemical inertness pose challenges in processing. In this study, diamond films were efficiently and gently ground using a grinding wheel containing nickel-plated diamond abrasives, thanks to the catalytic effect of the nickel plating.

Summary: A novel brazing technology using a modified Ni-Cr-W filler alloy is presented for brazed diamond grinding wheels. Mechanical characterization shows that the diamond brazed with the new technology exhibits higher static pressure strength and impact toughness than those brazed with conventional vacuum brazing technology. Raman spectroscopy reveals decreased graphitization of diamond brazed with the novel technology. Moreover, residual stress is reduced after brazing. Microstructure analysis confirms metallurgical bonds and the formation of W-C compounds and bonding phases between diamond and the modified alloy. The grinding test demonstrates improved service life, increased machining efficiency, and reduced abrasive invalidation rate for the grinding wheel prepared by the new brazing technology.

Summary: Fiber-reinforced silica ceramic matrix composites have gained attention for their applications in aeronautics, but the machining properties and mechanisms remain unclear. A full-factor grinding experiment was conducted to study the material's machining characteristics, revealing a correlation between surface roughness changes and an increase in grinding force, mainly due to fiber fracture.

Summary: Vitrified bond CBN grinding wheel specimens with adjustable porosity were prepared by controlling the dextrin content and forming pressure. The results showed that the porosity of the specimens increased with the increase in dextrin content, and decreased and then increased with the increase in forming pressure. The grinding experiments revealed that the dextrin content had a negative correlation with grinding force and temperature, while the forming pressure had an initial increase and then decrease effect on grinding force and temperature. The surface roughness of the specimen after grinding was found to be smaller than that before grinding, and the roughness of the workpiece surface increased with the increase in porosity of the specimen.

Summary: The study investigated the grinding performance of TiC-Steel cermet using a customized vitrified bond cBN wheel. Results showed that the main removal modes of TiC-Steel cermet are plastic removal of steel phase and brittle fracture of ceramic phase. Surface roughness parameters increase with grinding depths and decrease with spindle rotation speed, with feed rate having less impact on surface quality. Optimal processing parameters were determined to achieve the best surface quality and lowest grinding force.

Summary: Diamond grinding wheels have become the main tool for processing hard and brittle materials. This paper proposes a novel laser simulation bird feather-structured bronze bond diamond grinding wheel, which provides excellent drag reduction and diversion effects based on bird feather structure. The grinding performance of this feather-like structured grinding wheel (FLSGW) is compared with a V-shaped structured grinding wheel (VSSGW) and a traditional grinding wheel (TGW) when grinding silicon carbide ceramics. The results show that FLSGW significantly reduces grinding forces, improves workpiece surface quality, and has less abrasive wear compared to VSSGW and TGW.

Summary: This paper presents an experimental study on the formation mechanisms of surface white layers in high-speed machining of hardened steel. The effects of cryogenic liquid nitrogen cooling and dry cutting conditions on the characteristics of the white layers are compared. The results show that white layer hardness is increased and grain size is decreased under cryogenic cooling. Severe plastic deformation is found to be the dominant reason for white layer formation.
