The invention discloses an electric arc additive and subtractive composite manufacturing process planning method and system. The method comprises the steps that component modeling is conducted; slicing and layering to obtain contour coordinates; collision interference detection; formulating an additive and subtractive process alternating sequence; constructing a planning mathematical model; and solving the mathematical model to obtain a process planning sequence. Compared with the prior art, the method is not only suitable for complex structural parts with columnar characteristics, but also can be expanded to complex structural parts with other geometrical characteristics; meanwhile, the invention develops an additive and subtractive composite manufacturing process planning system, an optimal additive and subtractive composite manufacturing process scheme with the shortest alternative time of additive and subtractive procedures as a target is formulated by introducing a component to be formed, and additive an
