The invention discloses a multi-directional numerical control linkage precision forming process of a transmission planetary carrier. The process is characterized in that a heated metal bar is formed through numerical control linkage of an upper punch, a front punch, a rear punch, a left punch and a right punch in five directions, and a precise forging of the transmission planetary carrier with thecomplicated shape is prepared in a single station and through one-time heating and multi-directional forming; and the front punch, the rear punch, the left punch and the right punch in a die are arranged in four side square holes in a female die, and are not separated all the time in the forming process. The forging forming planet carrier forge piece is small in machining allowance, the production efficiency is greatly improved, the cost can be reduced to a great extent, and a certain foundation can be laid for mass production of the current part.
