Abstract The rationality of a tolerance allocation plan ensures the efficiency and quality of aircraft products. A typical
aircraft wing box is selected as the study object, and its assembly processing technique is analyzed. Based on the three
dimensional tolerance analyzing software 3DCS, the 3D tolerance analyzing model is built and the assembling process is
simulated. Then, the tolerance allocation plan is designed and optimized. Besides, the structuring display of the 3D tolerance
model is implemented and the mechanism of interactive rapid adjustment for the model is established based on the
development tool CATIA CAA.
