摘　　要：目的:为验证铣削加工面齿轮齿面的精度是否满足相应标准。方法:首先由包络法以及齿轮啮合基本原理,建立正交面齿轮齿面方程,从而建立面齿轮模型;通过五轴数控机床铣削加工了三齿面齿轮,通过3D扫描仪获取实际加工出的齿面,并与理论齿面进行对比分析。结果:铣削加工出的面齿轮齿面在齿顶和齿根位置精度较低,不能满足相应标准。结论:铣削加工面齿轮齿面需要合理规划刀具在齿根及齿根位置的路径,以提高面齿轮齿面的铣削加工精度。Objective: To verify whether the accuracy of the milled and machined face gear tooth face meets the corresponding standard. Method: Firstly, the orthogonal face gear tooth equation was established by the envelope method and the basic principle of gear meshing, so as to establish the face gear model;the three-tooth face gear was milled by a five-axis CNC machine, and the actual machined tooth face was obtained by a 3D scanner and compared with the theoretical tooth face for analysis. Results: The accuracy of the milled face gear tooth surface in the tooth top and tooth root position is low and cannot meet the corresponding standard. Conclusion: Milling the face gear tooth surface requires reasonable planning of the tool path in the tooth root and root position to improve the milling accuracy of the face gear tooth surface.
