“…Currently, Cubitron™ II grinding wheels are manufactured in the following types: 1, 4, 5, 11, 12, and 27, although only the latter are low height. Up till now, the tests involving the processes of obtaining correct properties of the grinded surfaces, with the use of microcrystalline sintered corundum grinding wheels, have been described by about a dozen of authors [6][7][8][9][10][11][12][13]. However, those tests did not involve the Quickpoint technique.…”

This paper describes a simulation model of the process of developing steel rollers’ surface layer roughness obtained with Cubitron™ II grinding wheels by the Quickpoint technique, depending on the assumed grinding conditions. In particular, the authors present physical assumptions of the respective model, a conception and algorithm of its operation, and the results of simulation tests. The results were later verified in specific experiments by comparing the statistical average values of the selected ground steel rollers’ surface roughness parameters with the values generated by simulations

“…However, the soft measurement method using grinding power is less accurate than a dynamometer. Wang 26 and Yang 27 have proposed grinding force models for form grinding the involute gear with microcrystal corundum grinding wheels. The effects of grinding parameters, the edge density of abrasive grains and the geometric parameters of gears on the grinding force were described.…”

Grinding is an essential gear finishing method. Grinding force analysis and prediction are critical to understand grinding mechanisms. By using a geometry model for gear form grinding and surface grinding mechanisms, a theoretical model was established to calculate the gear form grinding force. By considering the complete tooth depth engagement between tooth grooves and wheel profiles during form grinding, three segments of the involute, transition arc and tooth bottom line, which were included in complete tooth groove profiles, were analysed using the model. Contact relations among the normal grinding depth, wheel equivalent radius, wheel linear velocity and wheel profile were obtained. In addition, grinding experiments were outperformed on the basis of the single tooth, and the unknown coefficients of the form grinding force calculation model were acquired. The effects of the grinding depth, feed speed and grinding speed on grinding force were analysed using the grinding force model. The comparison of the predicted values of the form grinding force model with the experimental results, indicated that the relative errors of tangential and normal grinding forces are within ±10% and ±12%, respectively. The results confirmed the accuracy of gear form grinding force calculation model. These findings play a key role in parameter optimisation during gear form grinding.

“…A large number of experiments have shown that because of the excellent hardness and heat dissipation characteristics, microcrystalline corundum grinding wheels are applied to many kinds of grinding methods. Wang et al studied the theoretical analysis and experimental verification of the grinding principle of the new microcrystalline corundum’s forming method [9]. Breitung-Faes et al studied the true grinding performance of molten corundum [10]; Yang et al explored the grinding performance of a new microcrystalline corundum grinding wheel for grinding automotive gears [11].…”

(1) The alloy material 20CrMnTiH is widely used in gear manufacturing, but difficult to process, and its quantity (efficiency) and quality (surface quality) are generally negative correlation indicators. As a difficult but realistic problem, it is of important practical significance to explore how to efficiently grind high-precision low-carbon alloy gear workpieces. (2) Firstly, the pixel method was applied to analyze the grinding principles and explore the grinding parameters—the grinding wheel speed and grinding wheel frame moving speed—as well as the feed rate, which impacts the grinding indicators. Secondly, based on the ceramic microcrystalline corundum grinding wheel and the 20CrMnTiH gear workpiece, controlled experiments with 28 groups of grinding parameters were conducted. Moreover, the impact curves of the grinding parameters on the grinding indicators—the grinding efficiency, grinding wheel life, and surface roughness—were obtained by the multiple linear regression method. Finally, the multi-objective optimization method was used to comprehensively optimize the grinding process. (3) Compared with the traditional grinding process, under optimized grinding parameters, the 20CrMnTiH gear workpieces have a lower surface roughness and a longer grinding wheel life, and require a shorter time to achieve grinding accuracy. (4) The grinding experiments showed that the grinding parameters are linearly related to the grinding indicators. The optimization results show that the precision, efficiency, and economy of the 20CrMnTiH gear grinding process have been improved via the comprehensive optimization of the grinding parameters.
