摘要

针对镜像加工过程中结构变形致使加工精度难以控制的问题，建立了基于旋量理论的镜像加工剩余壁厚运动学模型，综合考虑零件加工要求及镜像约束关系，提出了镜像加工“支撑–铣削”轨迹生成方法，建立了针对工件变形补偿的镜像支撑轨迹修调模型，实现了镜像加工“支撑–铣削”轨迹自动修调。栅格壁板镜像加工验证试验结果表明，提出的镜像加工“支撑– 铣削”轨迹生成和自动修调方法可以满足镜像加工剩余壁厚要求。

Abstract

To solve the problem of datum failure caused by deformation of workpieces during mirror milling

a kinematic model of wall thicknesses for mirror milling based on screw theory was established. Considering comprehensively of parts machining requirements and mirror milling constraints

a“ support–milling” trajectory generation method was proposed. Meanwhile

a supporting trajectory adjustment model for deformation compensation was developed. Then automatic trimming of the“ support–milling” trajectory for mirror milling was realized. The results of the verification experiments on the grid mirror milling of thin-walled parts show that the “support–milling” trajectory generation and automatic adjustment method for mirror milling can meet the requirements of the wall thickness for mirror milling.
