| Abstract |
Abrasive jet precision finishing is a new machining method, which injects slurry of
abrasive and liquid solvent to grinding zone under without feed condition. The machining is
simulated by Finite Element Method (FEM) in the paper. Hydrodynamic pressure on modeling of
wedge-like grinding zone between wheel and workpiece on abrasive jet finishing with wheel as
restraint was established and simulation, based on Navier-Stokes and continuity equations. The liquid
hydrodynamic pressure distributing principle and affecting factor were investigated. The relation
hydronamic pressure with grinding wheel velocity was stimulated and verified experimentally. The
experiment results show that the simulation results are agreement with experiment, so the simulation
model can well forecast hydrodynamic pressure distribution at contact zone. |
