All fields of science do not stand still and develop. The industrial revolution involves a new approach to production, based on the mass introduction of information technologies, this also refers to mechanical transmissions with gears and more specifically to planetary precessional gears. The implementation of these gears involves the study of scientific research in the field of precessional gear manufacturing technology. Several technologies have been created, for mass and large series production. The given article presents a new step-by-step method for manufacturing gears for small-scale production on CNC machining centers. The results of the proposed technology and the next steps that were followed in the design of the precessional gear machining process are presented. CAM Parts were identified which were made in CAD software, then with the help of CAM, a new gear processing technology was obtained.
