Aiming at under-process planning and process planning optimization in the manufacturing process of complex part with this hybrid manufacturing technology,a hybrid process planning algorithm for additive and subtractive manufacturing is presented in this paper. By performing four steps including part decomposition,building direction determination,additive and subtractive operation sequence generation and operation sequence optimization,a proper operation sequence with time optimization is generated at last,which can realize the precision fabrication of complex part. Moreover,the experimental case is performed and which demonstrates the feasibility and advantage of present algorithm.
