摘　　要：概括分析了薄壁整体结构件切削加工的特点和难点.以高速铣削铝合金三连波导试件为例,通过采用适当的装夹方法,合理安排工序,优化铣削方式和走刀路线,合理选用刀具,优化切削用量,合理冷却润滑,在控制变形使加工质量符合要求的前提下,省略了中间热处理工序,加工时间低于普通铣削时间的三分之一.实践经验和试验数据表明,高速铣削薄壁整体结构件应采用高切削速度、大进给速度及小轴向切深,可供推广应用高速铣削之参考.This paper presents a brief analysis of the features specialties and problems of machining of integral parts with thin walls. The high-speed milling of the aluminum alloy tri-wave-guide samples is presented as a case study. Its machining time reduces to about one third of conventional speed milling time under conditions of keeping small cutting deformation and high machining quality, and omission of the heat treatment working procedure. This is achieved through suitable clamping of the samples, suitable cutting procedure, optimizing of milling art and tool path, reasonable choice of cutting tool, optimizing of cutting parameters, suitable lubricating and cooling. The practical experiences and measure- ment data obtained show that high cutting speed, high feed rate and small cutting depth should be adopted for high speed milling of integral parts with thin walls. This could promote the implementation of high speed milling.
