The invention relates to the field of production machining mechanical equipment and discloses full-automatic feeding, cutting and receiving equipment. A material slot of a feeding device of the full-automatic feeding, cutting and receiving equipment is provided with a shifting mechanism consisting of a shifting fork and a shifting rod. The end of the shifting mechanism, which corresponds to a rear baffle plate of the feeding device, is provided with a leveling mechanism. A feeding bracket at the side of an unloading mechanism, which is correspondingly connected with a tube cutting device, is provided with a clamping mechanism. A lower roller and a side roller which are connected are arranged in the unloading mechanism. A split clamp of the tube cutting device is arranged on a tube cutting bracket through a trapezoid block. A recovery device consists of a recovery mechanism and a return mechanism, wherein the recovery mechanism is arranged at one side of the split clamp in a leveling mode; and the return mechanism is arranged on a recovery bracket at the rear end of the recovery mechanism. A brush wheel is arranged in the return mechanism. A machining method of the equipment comprises the steps of adding, aligning, feeding, cutting and receiving. The full-automatic feeding, cutting and receiving equipment is smooth to feed materials and is clear to separate the materials, so that resource waste is avoided, the machining procedures of the engineering are reduced, the cutting quality is improved, both manpower and material resources are saved and the production efficiency is improved.
