The Modeling and Finite Elements Simulation for Pressure Field of Abrasive Jet Precision Finishing With Grinding Wheel as Restraint

It is innovative to combine abrasive jet machining and conventional grinding together in this thesis. And it realizes a new sort of grinding wheel restricted with abrasive jet processing. The three-dimensional mathematical model of hydrodynamic pressure of wedge-like grinding zone between grinding wheel and workpiece on abrasive jet finishing with wheel as restraint was established, and the finite elements simulation analysis for the hydrodynamic pressure was implemented. This paper investigated the liquid hydrodynamic pressure, the regularities of distributing of velocity, influencing factors and the affection for processing technique.
