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.
