“…Fig. 2 shows the virtual model of a CNC hypoid generator [16]. The machine tool has 6 coordinate axes: the cutter is located on the left side of the machine and moves upward and downward as well as forward and backward along Y axis and Z axis, and it rotates along C axis; the gear is located to the right of the cutter and moves along X axis and swings around Y axis along B axis and rotates around A axis.…”

“…In order to increase the high load capacity, good strength and high precision transmission of the gears, the gear surfaces are often tempered and treated to achieve the appropriate hardness [12][13][14] . However, the surface quality of the gears has been reduced after the heat treatment processing [15][16][17] . Therefore, the gear surface after heat treatment processing will be grinded to improve the surface quality and the time-life of the gear.…”

The non-Newtonian fluid is one type of shear thickening fluid which applied to process the complicated products. In this study, the new method of shear thickening fluid polishing (STFP) was used to polish the alloy steel SCM435 gears and the principle and performance of polishing process were also introduced. In the polishing process, the inclination angle of gears was believed to be an important parameter that affects the pressure and surface quality at different position on the tooth surfaces because it determines the contact between the polishing fluid and the tooth surface of the gear. The influence of the inclination angles on the pressure distribution and characteristics of fluid flow was performed by simulation process. The inclination angles of 0, 4, 8, 12, 16, 20 and 24 degrees were chosen in this study. As a result, the best inclination angle of gears is about 16 degree in the machining process. The tooth surfaces of gear have been in contact with the polishing fluid and the produced pressure reaches of 14.88 kPa. In addition, the influence of polishing speed on pressure were carried out in this study when inclination angle was established about 16 degree. The produced pressure on tooth surfaces increased with increasing the polishing speed. The results indicated that the different polishing speed also greatly affects the surface quality and machining efficiency. Therefore, the suggested machining method can become a suitable processing method for polishing the complicated products.

In order to improve the machining accuracy and production efficiency of face gear, a generating grinding method for face gear using cubic boron nitride (CBN) wheel is studied in this paper. The mathematical model of the CBN wheel profile is derived based on face gear grinding principle and theory of gearing. Taking the demands of machine motion during face gear grinding into account, a five-axis face gear grinding machine is developed. Then, the mathematical model of the ground face gear and the grinding method are proposed based on the structure of the machine. For reducing the face gear tooth profile errors induced by installation errors, an error analysis model of face gear grinding is established; the effects of installation errors on tooth profile errors are analyzed. The CBN wheel was manufactured, and the grinding experiments were performed on the self-developed grinding machine. The processing parameters of face gear grinding were amended according to the tooth flank measurement results obtained from coordinate measuring machine. The ground tooth profile deviation was reduced significantly after processing parameters amendment. Experiment results demonstrate that the generating grinding method is an effective approach to achieve the precision grinding of face gear.
