According to the prominent theoretical demands and technical frontiers in meeting the “4H” performance requirements for the manufacturing of robotic reducer bearings, a novel machining method named as strengthen jet grinding has been proposed to study the evolutionary mechanism of interface morphological structure in micro-mesoscopic scale, thereafter the generic theoretical and technical difficulties during the manufacturing processes of reducer bearing can be solved, and a high-efficient machining method capable of the shape/property controlling can be achieved subsequently. This research includes such topics as: Establishing a mapping relation model of multi-phase flow energy transmission and revealing the working mechanism and characteristic principles of abrasive impacting on the machined surface; Investigating the tribochemical machining principle and its developmental mechanism at the contact area of surface layer, then identifying the coupling rules between abrasive contacting statues and their strengthening effectiveness on the bearing material surface\boundary layer; Developing the stress-strain dynamic constitutive modelling method of bearing material in the specific environments of extremely strain rate, and then quantifying the interference effects of morphological structure on the metastable propagation of waterjet shock waves; Assessing the control strategies aiming at the critical states of abrasive-jet impacting deformation, building up a research system concerning with the machining effect of strengthen jet grinding and the evolutionary mechanism of interface layer morphological structure as the robotic reducer bearing oriented, and then realizing the optimization scheme of grinding parameters eventually. This research prompts the theoretical developments of strengthen jet grinding, so that it could be highly academic-valued due to its thoroughly clarification of turbulent shock waves, abrasive-impacting-produced deformation, grinding energy transmission, dynamic constitutive modelling, and multiphase media coupling mechanism; thus more key measures could be presented systematically to improve the surface machining quality, material properties, and working capabilities of robotic reducer bearing. This research deserves great significance to deal with the theoretical and technological difficulties in the manufacture domain of core products in high-end equipment as respected.
