摘要

航空发动机叶片的高效率自动化抛光是替代人工打磨、保证精加工型面质量的重要手段。本研究在前期研制的阵列加工机床上，针对多主轴阵列抛光时由批量叶片制造误差引起的抛光轨迹自动化调整需求，开展待抛光叶片变形分析及进排气边关键区域的抛光工艺试验，由此建立以抛光去除量差异最小为目标函数，表面粗糙度为约束条件的阵列抛光轨迹调整算法，并利用数控系统坐标转换功能实现 G 代码的自动调整。在保证阵列抛光精度及表面粗糙度的前提下，达到高效率多主轴同步抛光的目的。采用 4 件典型叶片进行阵列抛光验证，抛光后线轮廓度≤0.032 mm，表面粗糙度 R

0.4 μm，平均单件叶片抛光工时达到 2.75 min。

Abstract

High efficiency automatic polishing of aero-engine blade is an important means to replace manual polishing and ensure the quality of finish machined profile. In this paper

blade measurement analysis and polishing experiment for leading/trailing edge are carried out on the array machining machine tool. Therefore

the array polishing path adjustment algorithm with the objective function of minimum polishing removal difference and the constraint condition of surface roughness is established

and the coordinate transformation function of NC system is used to realize the automatic adjustment of G-code. On the premise of ensuring the polishing accuracy and surface roughness

the purpose of high-efficiency multi-spindle synchronous polishing is achieved. Four typical blades are used for array polishing verification

their linear profile is no more than 0.032 mm and the surface roughness is R

0.4 μm. The average polishing time of a single blade is 2.75 min.
