There are many factors that affect the surface quality of aluminum alloy by abrasive water jet polishing.This paper analyzes the influence of four process parameters,namely jet pressure,target distance,jet angle and abrasive flow rate,on the polishing quality.By using the orthogonal experiment and range analysis method,it has found that the main order of the influence of these process parameters on the surface roughness of aluminum alloy workpiece by abrasive water jet polishing is target distance,jet pressure,jet angle and abrasive flow rate Abrasive flow rate,jet angle.The empirical model between workpiece surface roughness and influencing factors is established by multiple regression analysis,which has great practical value for surface treatment of aluminum alloy automobile wheel hub.
