The invention discloses a cavity partition inserting and milling cutter path planning method based on maximum cutting wrap angle constraining. At first, an inserting and milling cutter path of a simple geometric shape cavity based on concentricity is generated, the boundary angle is used for replacing the cutting wrap angle to constrain cutter path planning, the maximum cutting wrap angle is set,according to the cavity outline, the cutter radius, the machining allowance and the radial milling width, the concentric position and the number of the concentric inserting and milling path meeting limitation of the maximum cutting wrap angle are determined, according to the cutter radius, the machining allowance and the cavity boundary, the area which the cutter can reach is determined, and by trimming the invalid arc track, the effective initial cutter paths are generated finally; and the simple geometric shape cavity based on the concentricity is divided into a plurality of basic modes, thevarious effective initial
