摘　　要：航空产品各组件对合面的形位公差要求很高,传统的手动及半自动加工方法效率低、精度差,很难满足任务需求。为了提高某大型飞机机翼发房尾舱与中外翼的对合精度,本文基于逆向工程技术提出一种自动测量技术,与数控机床结合,进行对合面铣削制孔加工的解决方案。根据工艺需求,利用激光扫描仪实现空间大部件对接面轮廓尺寸检测、基准提取和铣削量计算的方法,并通过试验进行了验证。结果表明,该系统显著提高了机翼发房尾舱与中外翼的装配精度和装配效率,具有很高的应用价值及推广意义,同时对其他复杂结构件的数字化设计、加工技术研究也有着积极的促进作用。The shape-position tolerance of the joint surface of each component of aviation products is very high.The traditional manual and semi-automatic processing methods have low efficiency and poor accuracy,and it is difficult to meet the task requirements.To improve the alignment accuracy of the tail cabin and the middle and outer wings of a large aircraft wing,this paper proposes a solution based on reverse engineering technology to combine automatic measurement technology with CNC machine tools for milling holes on the joint surface.According to the process requirements,the laser scanner is used to realize the method of contour size detection,reference extraction,milling amount calculation of large space parts,which is verified by experiments.The results show that the system significantly improves the assembly accuracy and efficiency of the tail cabin and the middle and outer wing,and has high application value and popularization significance.At the same time,it also has a positive role in promoting the digital design and processing technology research of other complex structural parts.
