“…A face gear tooth is considered an undevelopable ruled surface according to the theory proposed by Litvin [1][2][3], which limits the development of new face gear generation methods. However, most manufacturing methods for face gears currently depend on this theory [4][5][6][7][8][9][10].…”

“…However, this method can only be used for soft or low-precision tooth surfaces. The tools used to generate face gears containing hard or high-precision tooth surfaces are worm cutters or grinders [10] and disk cutters or grinders [5][6][7][8][9], which both duplicate the involute of the pinion. Although the indexing motion of the worm cutters/grinders is continuous, the generated surfaces are in point contact, the tool needs transverse motion in the longitudinal direction to process the whole tooth surface, and the processing efficiency is not very high.…”

The conventional tooth surface of a face gear is difficult to manufacture, and the cutter is not uniform even though the parameters of its mating pinion slightly change. Based on the analysis of the features of the tooth surface, a new developable ruled surface approach is proposed that defines the tooth flank of the face gear, for which the most important feature is that it could be generated by a straight-edged cutter. This study presents mathematical models of the cutter and the new tooth surface and the corresponding deviation, correction and generation method for this surface, which are investigated through numerical examples. The manufacturing process is simulated by VERICUT software, and the results demonstrate that even when the principle deviation is added to the machined deviation, the absolute deviation is on the microscale. The meshing and contact simulation shows that the new surface could obtain good meshing performance when the number of face gear teeth is greater than three times the number of pinion teeth. This research provides a new method for manufacturing face gears.

“…However, most manufacturing methods for face gears currently depend on this theory. [4][5][6][7][8][9][10] The surface of a face gear tooth is defined by it mates with a spur pinion. Hence, the simplest method for machining a face gear is the application of a shaping device that is identical to the pinion.…”

The conventional tooth surface of a face gear is difficult to manufacture, and the cutter for the face gear cutting is not uniform even though the parameters of the pinion mating with the face gear slightly change. Based on the analysis of the geometry features of the tooth surface, a new developable ruled surface is defined as the tooth flank of the face gear, for which the most important geometry feature is that the flank could be represented by a family of straight lines, hence it could be generated by a straight-edged cutter. The mathematical models of the new ruled tooth surface, the cutter and the generation method are presented, the deviation between the ruled surface and the conventional surface, the correction of the ruled surface to reduce the deviation are investigated through numerical examples. The manufacturing process is simulated by VERICUT software, and the results demonstrate that even when the principle deviation is added to the machined deviation, the absolute deviation is on the micro-scale. The meshing and contact simulation shows that the new surface could obtain good meshing performance when the number of face gear teeth is greater than three times the number of pinion teeth. This research provides a new method for manufacturing face gears.

This article presents a new model of the flat surface grinding process vibration conditions. The study establishes a particular analysis and comparison between the influence of the normal and tangential components of grinding forces on the vibration conditions of the process. The bifurcation diagrams are used to examine the process vibration conditions for the depth of cut and the cutting speed as the bifurcation parameters. The workpiece is considered to be rigid and the grinding wheel is modeled as a nonlinear two-degrees-of-freedom mass-spring-damper oscillator. To verify the model, experiments are carried out to analyze in the frequency domain the normal and tangential dynamic grinding forces. The results of the process model simulation show that the vibration condition is more affected by the normal component than the tangential component of the grinding forces. The results of the tested experimental conditions indicate that the cutting speed of 30 m/s can permit grinding at the depth of cut up to 0.02 mm without sacrificing the process of vibration behavior.
