Summary: The study aims to compare the performance of mechanically refined abrasive grits and artificial diamonds in milling and grinding, and investigate the impact of bonding system on wear. The findings indicate that diamond is the best choice for non-ferrous metals, but performs inferiorly to aluminum oxide grits at high cutting speeds on ferrous metals.

Summary: This study used a two-phase flow of fluid abrasive to investigate the cutting force of abrasive flow machining (AFM). The slipping cutting factor and cutting factor were defined for AFM, and the theoretical equation for calculating these factors was given. Results showed that the finishing force of AFM is proportional to the pressure of the flow field on the workpiece surface, and the abrasive phase cutting factors are influenced by factors such as abrasive particle size and mass mixing ratio.

Summary: This paper introduces a novel grinding wheel composed of porous diamond abrasive grains for better ultra-precision machining. Thermochemical etching is used to produce porous diamond grains of varying corrosion levels. The cutting and wear mechanisms of these grains are investigated through molecular dynamics simulations and single-grain scratch tests.

Summary: This paper proposes a novel method to describe the contact behavior exerted by ultrasonic vibration in multiple directions. The effects of ultrasonic vibration on scratch hardness with varying scratch velocity and cutting depth are evaluated based on the developed model and the UVAS test. The study provides an effective tool to capture the instantaneous contact state with a complex moving path and predicts the scratch hardness under ultrasonic vibration through common scratch tests.

Summary: The article evaluates the roughness of parting surfaces using abrasive water jet technology for different materials. The feed speed of the cutting head is adjusted to achieve the desired roughness, taking into account the stiffness of the material being cut. Non-contact and contact methods are used to measure the roughness parameters of the divided surfaces.

Summary: In this study, a single grit grinding experimental method is proposed to investigate the material removal behavior of robot abrasive belt grinding (RABG) on nickel-based superalloy. Ceramic alumina grits are used to scratch the superalloy in the experimental setup of RABG. Four material removal parameters, including real cutting depth, number of cutting edges involved in grinding, effective cutting area of cutting edges, and pile-up ratio, are quantitatively described to characterize the material removal behavior. The experimental results show that the grits exhibit good cutting performance and the dynamic changes of cutting edges significantly affect the material removal. Moreover, this study analyzes the differences between RABG and wheel grinding (WG), investigates the effect of cutting depth on material removal, and determines the factors influencing the material removal ability by evaluating the material removal ability of different grits.

Summary: This study reveals the wear mechanisms of the abrasive wheel, including attrition wear, fracture and pulling-out of abrasive grains, material adhesion, clogging, and chemical wear. With the degradation of abrasive grain, the wear mode successively changes from attrition wear to grain fracture and pulling-out.

Summary: Previous research on grinding has not fully studied the surface generation mechanism and elastic recovery due to the limitations of single grit scratching. This investigation compared single scratches with adjacent scratches and found that scratch speed and separation distance have significant effects on cutting forces, pile-up area ratio, groove depth, and sub-surface deformation. The experiments also showed that the spacing between two subsequent scratches can greatly affect the scratched surface quality.

Summary: This study aims to investigate the wear characteristics of a diamond grinding wheel and its effects on the surface characteristics and grinding forces of cemented tungsten carbide cutting inserts. The measurement of grinding forces, surface and edge quality parameters, as well as the analysis of grain protrusion and active cutting edges, were conducted. The results showed that there was a decrease in grain protrusion and an increase in grinding forces in the initial cutting stage, but self-sharpening phenomenon occurred after grinding of a larger volume, leading to increased grain protrusion and reduced grinding forces, as well as improved surface roughness of the inserts.
