摘要：
A cavity optimization method based on the principle of reverse deformation was prompted in this paper. In the reverse deformation method, the displacement which represents the nonlinear shrinkage was superposed on the initial profile of cavity and compensated the shrinkage of wax and alloy solidification. Moreover, an estimation algorithm was prompted to calculate the displacement based on reverse engineering, and its key technologies such as blade measurement, model registration, and statistical analysis of the displacement were investigated. Finally, a sample application was presented for demonstration in this paper.
