The invention provides an additive and subtractive composite manufacturing method and system for a centrifugal wheel structure, and belongs to the field of part manufacturing. Performing characteristic decomposition on the centrifugal wheel three-dimensional model to obtain a bottom circular ring characteristic, a central circular ring characteristic, a top circular ring characteristic and a central disc characteristic; based on the bottom circular ring characteristics and the center circular ring characteristics, a bottom circular ring and a preliminary center circular ring are subjected to additive manufacturing from bottom to top and from inside to outside; based on the characteristics of the center disc, a preliminary center disc is manufactured through radial rotation additive manufacturing around the preliminary center circular ring; based on the characteristics of the central disc, blades are manufactured in the initial central disc in an additive and subtractive alternating mode, and the central disc
