In order to realize the compound process of rapid forming and high precision milling for complex pieces, our assignment group developed a five-axis additive-subtractive hybrid machining center. Based on the five-axis additivesubtractive hybrid machining center, the developing process and integrating control principles are expounded, and the control method of total precision is analyzed. Furthermore, the relevant experiments were carried out. The tapered bench specimens in the acceptance criteria of aerospace engineering impeller and five-axis machine tool are used for material subtraction trial manufacturing. We carried out some additive manufacturing experiments for the impeller blades and S specimens, algorithms optimization of generating additive manufacturing path were also applied. The expected machining performance is preliminarily acc omplished.
