Based on the principle of gears, the mathematical model of the tooth surface of the planer is established by the method of gear grinding. Then the mathematical model of the power skiving is derived, and the influence of the curve of different grinding wheels and the parameter compensation of the machine on the tooth profile error of the internal spur gear is discussed. The optimization part is divided into two parts. Firstly, the shape of the grinding wheel is changed to optimize the tooth profile error of the workpiece gear, and then the second optimization is performed based on the first optimization result. The second time optimization is mainly based on the power skiving workpiece compensation angle for optimization analysis. The optimization purpose is to improve the accuracy of the tooth profile error of the internal spur gear. After the optimization calculation, the optimal parameter setting can be obtained to determine the optimization. After the process, the author also writes the optimization program analysis, and performs the power skiving to create the tooth profile error analysis of the internal spur gear. The two sets of different tool and workpiece gear parameters are analyzed respectively, and finally two set of optimal grinding wheel profile curves and power skiving are obtained. The compensation angle parameters in the motion are compared and the correctness of the analysis results is verified.According to the accuracy standard of the gear and the variable factors in the derivation process,the optimal design of the tooth profile of the power skiving cutter is proposed based on the tooth profile error of the workpiece.
