In order to further improve the processing quality of the blisk used in the intelligent transplanter and the whole machine efficiency of the transplanter, the research on of the NC machining parameters of the blisk was optimized. By selecting a model of intelligent transplanter, fully mastering modern NC machining technology on the basis of understanding briefly its key parameters and working principle, the processing parameters of the blisk on the intelligent transplanter were optimized. The mathematical model was established by the objective optimization function, and the 3D physical model of the key components of the blisk was given by the drawing software UG and then the process test was made by planning the processing route. The research showed that the processing precision of the blisk could be improved by about 10% before the parameter optimization, and the manufacturing cost of the blisk could be reduced by about 3%, the durability of the blisk and the whole machine working efficiency for the intelligent transplanter has been improved according to the rational selection of the numerical control processing procedures and the cutting tools, it proved that the parameters optimization research and test have important significance on the practical application.
