“…For example, the increase in the negative rake angle leads to greater plastic deformation [21] and has an influence on chip formation [13,22,23]. Gao et al [24] presented the influence of the active abrasive grains orientation on the performance and material removal rates during the honing process. By means of FEM simulation, it was possible to analyze the variation of material removal, material removal rate, surface roughness and honing force.…”

The shape of the cutting blades of the abrasive grains has an influence on the material separation process in the machining zone. The paper analyzes the influence of the geometrical parameters of the abrasive grains (rake angle γ, apex angle ε, opening angle α), as well as width bz and length bb of the cutting zone on the material removal efficiency. The material removal efficiency was determined taking into account the volume of the removed material VG and the volume of lateral piles-up VR. The analyses were carried out on the basis of the results of experimental and simulations using the finite element method. The relationship between the selected geometric parameters characterizing the cutting zone and the coefficient characterizing the efficiency of the material removal process was determined. A strong influence of the opening angle α as well as the width bz and length bb of the cutting zone on the material removal process by abrasive grain was demonstrated. It was observed that the wide cutting edge, and thus the large opening angle α of the grain, reduced the size of the pile-ups and more effectively removed the chip material.

Structured grinding wheel has obvious advantages in reducing grinding force, and the structural parameters of grinding wheel have important in uence on the reduction effect of grinding force. In order to determine the in uence law of structural parameters on grinding force, the following theoretical modeling and experimental research work are carried out in this paper. Firstly, single grit scratching experiments of the workpiece material are carried out to determine the critical cutting depth for ploughing and cutting transition. The in uences of structural parameters on the maximum undeformed chip thickness and the average contact arc length during grinding are analyzed in detail. The abrasive grains are simpli ed into a cone with a cone apex angle of 120 degrees, the surface topography model of the structured grinding wheel is established according to the measured results of the distribution law of abrasive grains on the surface of the grinding wheel and the structural characteristic parameters.Combined with the grinding force model of single abrasive grain in ploughing and cutting stages, the calculation model of grinding force in the grinding process of straight groove structured grinding wheel is established. Finally, grinding experiments are carried out to verify the accuracy of the theoretical grinding force model. The results show that the calculated values of grinding force are in good agreement with the experimental values, and the maximum calculation errors of tangential grinding force and normal grinding force are 14.5% and 11.8%, respectively. It is found that when the intermittent ratio of structured grinding wheel is constant, the groove width has little in uence on grinding force. However, when the groove width is constant, the intermittent ratio has a great in uence on the grinding force, and with the increase of the intermittent ratio, the grinding force decreases obviously. grinding force, but the increase of intermittent ratio will also aggravate the wear of grinding wheel. How to reasonably design the structural parameters of grinding wheel needs further research.

CNC powerful gear honing can comprehensively improve the tooth surface performance and is widely used in the finishing process of high-performance gears in the transmission system of new energy vehicles. Accurate evaluation of gear honing processing quality has important engineering application value for popularizing the process of "honing instead of grinding". In this paper, 12 factors, such as abrasive particle size, are determined qualitatively by analyzing the factors affecting gear honing accuracy, tooth surface quality and machining efficiency. Based on trapezoidal fuzzy analytic hierarchy process (Tra-FAH) and set pair analysis method (SPA), a quantitative evaluation model of CBN abrasive micro edge honing quality is established. Through the influence factor weight and key factor sensitivity analysis, it is quantitatively determined that the honing process parameters and abrasive particle size, abrasive particle shedding, abrasive particle breakage and other factors are the key factors affecting the honing quality. Taking the particle size factor as an example, the machining experiment and analysis show that the model can correctly evaluate the honing quality of high quality hardened gears and can be used to study the mechanism of honing characteristics and improve the comprehensive quality of powerful gear honing.
