Composite materials have high specific strength

specific stiffness and designability

which have been widely used in aircraft manufacturing. However

due to the influence of springback deformation and other factors

the geometric accuracy of parts is low

and the problem of composite material deformation correction urgently needs to be solved. Aiming at how to standardize and rapidly build the mathematical model of composite material deformation correction process

this paper put forward the automatic tracking

the discrete points and so on to assist the generation of contour surface

proposed the merge sort method

interpolation search algorithm and so on to assist the generation of inner surface. Some surface processing methods used in mathematical model construction were listed

and the deformation correction system of composite parts was developed under CATIA environment. The overall efficiency is improved by 734.5% after modification

which shows that the method can construct the technological mathematical model efficiently and normatively

and improve the generation efficiency of technological mathematical model.
