Abstract: Z-shaped frame was laid-up and cured on the lay-up & curing tooling using unidirectional prepreg. The profile of part was measured by coordination measurement mechine (CMM), this paper analyzed the deformation of Z-shaped frame according to comparision measuring data of the part with theoretical profile of the part. The deformation contains springback between inner & outer flange and web of the part, deformation in the radius direction and deformation in the web direction of the part. Using the surface of frame which was compensated according to the part′s acceptance document to modify the design of curing tooling, a full-scale part was manufactured on curing tooling which has been compensated. The part was measured by CMM again, the result showed the validation of compensation to curing tooling surface, surface profile tolerance of the part conformed to the part′s acceptance document (±0.375 mm). Z-shaped frame matched shear tie and skin perfect when it was assembled.
