The utilization of automatic machines controlled numerically is significant for achieving flexible aircraft wing assembly. This paper presents all off-line programming and simulation system for flexible aircraft wing assembly, which is composed of two modules. The off-line programming module generates tool path of drills according to the 3D solid model designed in advance and the accurate position of each part which is provided by optical measuring machine, and then translates it to NC code with taking the process parameters into consideration. This paper details the second module, the visualized simulation module, which validates and optimizes the related assembly process. The scope of simulation covers three aspects, those are, the tool path simulation, NC code simulation and assembly environment simulation. The system is developed based oil CATIA and DELMIA. An example of an aircraft wing assembly process is used to illustrate the detail and advantage of the system.
