【Abstract】 On the basis of introducing several common used data acquisition methods in reverse technology,Free-form surface technology and curve fitting algorithm used at present were studied,and the methods in free-form surface reconstruction were proposed in this paper.By reversing the free-form surfaces of the port in tractor engine,the whole surfases of this part were reconstructed.更多还原
