Because the tooth surface micromorphology affects the performance of the gear and the finite element analysis and the grinding process of tooth surface through finite element analysis and simulation is complicated and time-consuming, the paper proposed a three-dimensional (3D) ultrasonic assistant grinding (RUAG) geometric simulation method to discover the micromorphology formation mechanism. Based on the motion path of a single grain, the 3D models of gear blank and the grinder was built. It helps to simulate the RUAG process. The morphologies of the simulated tooth surface were compared under conventional grinding (CG) and RUAG, which was consistent with the practice. It is proved that the geometric simulation method intuitively shows the micro dents on the tooth surface under different grinding parameters. The simulation method is helpful to analyze the surface morphology under different RUAG machining parameters and saves the cost and time of the actual production and processing.

“…With the wide application of superhard materials and complex alloys, the ultrasound-assisted grinding processing technology has been progressing continuously in order to adapt to the difficult machining of superhard materials as well as to the demand for high efficiency and high-quality production in modern manufacturing. Wen et al [10] explored the contact performance of ultrasound-assisted grinding surfaces and proposed a rough surface contact model suitable for this case. The correlation between cutting parameters and contact performance was investigated, and it was found that the abrasive grain interference motion in ultrasound-assisted grinding was conducive to the improvement of the contact performance of the surface.…”

The surface residual stress of the parts has an important influence on their performance. The generation mechanism of surface residual stress in ultrasonic vibration-assisted grinding (UVAG) of bearing steel was investigated, and the correlation between processing parameters and residual stresses was obtained. Based on the ultrasonic vibration-assisted grinding force and thermal model and the flow stress model considering the initial material microstructure, the mechanical and thermal stresses of the material were calculated. Finally, the theoretical model of residual stress is established based on the yield theory and experimentally verified. High-speed ultrasonic aerostatic spindle for ultrasonic vibration-assisted grinding, change the inlet pressure to realize the ultrasonic amplitude and frequency adjustment, the experimental results show that the cutting direction and the vertical cutting direction of the residual stress test results and the model prediction results of the average relative error of 11.4% and 11.7%, and the rule of change is more consistent. Based on the experimental results, the influence pattern of process parameters on the experimental results was analyzed. The results show that the residual compressive stress on the surface of ultrasonic vibration-assisted grinding is directly proportional to the grinding depth, feed rate, and inlet pressure of pneumatic ultrasonic wave, and inversely proportional to the linear speed of the grinding wheel. This study provides a theoretical basis for the analysis of UVAG residual stress and optimization of UVAG process parameters.

The precisely ground tooth surface of the spiral bevel gear still shows the thermal crack, and its micromorphology is the cause of high-frequency noise. The ultrasonic assistant grinding (RUAG) technology has the unique advantage of solving these problems. Therefore, this paper designed the split-type rotary device in which the disc grinder and amplitude horn are core components and bolted together. A deformation coefficient was proposed to calculate the strain stress of the disc grinder. Combined with the stepped horn resonant theory, the theoretical model of a multi-step rotating body can be used to calculate the frequency and amplitude of the grinder and horn. The harmonic response simulation was adopted to verify the theoretical results. The experiment proved that the device’s frequency, node, and amplitude are reasonable. The comparison results showed that the simulated frequency and amplitude were closer to the practical one. Moreover, the difference between them increased with the dimension of the device.
