The invention relates to a manipulator machining process, in particular to a manufacturing and assembling integrated forming process of a teaching manipulator, and the forming process can continuously manufacture and assemble components. The forming process mainly comprises the steps of (1) mold selection, specifically, a forming mold of a joint connection portion of the teaching manipulator is selected; (2) casting molding, specifically, molten aluminum alloy liquid is poured into the mold through high pressure and high speed to form the joint connection portion; (3) conveying of a formed part, specifically, the joint connection portion formed part is conveyed to an open working chamber through a sealed conveying channel; (4) punching, specifically, all formed parts are subjected to lamellar punching and then are conveyed or overall conveyed; (5) polishing, specifically, the formed parts are polished, cleaned, degreased, deburred, washed and drained off through aluminum alloy magnetic polishing equipment; (6) assembling, specifically, the joint connection portion, a power device and an execution component are assembled into a whole; and (7) detection, specifically, the assembled manipulator is controlled, and the performance of the assembled manipulator is detected. The teaching manipulator is rapidly formed through step-by-step machining, processing, assembling and other procedures.
