摘要

本文研究了圆弧齿迹(CATT)圆柱齿轮铣床的误差。采用低编号体阵列法建立了铣床的拓扑结构模型。利用D-H齐次变换矩阵建立铣床相邻零件间的坐标变换矩阵。基于拓扑结构模型和变换矩阵，建立了CATT齿轮铣床的综合误差模型。根据误差模型，铣削点的角度误差是运动部件角度误差的线性组合，而铣削点的位移误差与位移误差、运动部件角度误差、机床调节参数和齿轮几何参数有关。最后，讨论了CATT齿轮加工中刀盘误差对铣削点误差的影响。研究结果可为CATT齿轮铣床的误差分析、精度设计和几何误差补偿提供理论依据

Milling Machine Error Modelling and Analysis in the Machining of Circular-Arc-Tooth-Trace Cylindrical Gears

GEARS Summary This paper is to study errors of a milling machine used for the machining of Circular-Arc-Tooth-Trace (CATT) cylindrical gears. A topological structure model of the milling machine is established using the lower numbered body array approach. Coordinate transformation matrices between adjacent parts of the milling machine are set up by the D-H homogeneous transformation matrix. Based on the topological structure model and transformation matrices, a comprehensive error model of a milling machine used for the machining of CATT gears is established. According to the error model, the angle errors of the milling point are linear combinations of the angle errors of moving parts, while the displacement errors of the milling point are related to displacement errors, the angle errors of moving parts, the adjustment parameters of machine tools, and the geometric parameters of the gear. Finally, the influence of the errors of the cutter head on the milling point errors in the machining of CATT gears are discussed. The research can provide a theoretical basis for the error analysis, precision design, and the geometric error compensation of a milling machine used for CATT gear
