In this paper, the study is carried out on the parameters optimization of high speed milling deep hole and thin wall aluminum alloy parts in electronics industry. The material removal rate is chosen as optimization objective. The new cutting process optimization data filtration methods are put forward. Firstly, the maximal maximal spindle rotate speed of high speed machine tool and its critical depth of cutting are confirmed based on the theory of cutting stable region. Secondly, the cutting parameters are filtered with the cutting restraint conditions such as machining tool＇s power, surface quality, cutting tool＇s deformation and strength. The high speed milling parameters are filtered and optimized according to the model set up by this paper. The production practice shows that the method of cutting parameters optimization and filtration can ensure the machining precision and surface quality and improve the machining efficiency obviously.
