In order to discuss the machining mechanism and technology of abrasive flow machining for non-linear tube parts,a common rail tube was employed as the experimental subject.A self-devel-oped abrasive flow polishing solution was used to machine non-linear tubes,and the key processing parameters were obtained during the machining processes.Through the analysis of these processing parameters,dominant relationship between the surface roughness of parts and machining parameters was evaluated quantifiably,the impact of key processing parameters on surface precision of the parts was explored.It is concluded that the abrasive flow machining can improve non-linear tube parts sur-face quality obviously,and improve the working reliability and service life of non-linear tube parts. The experimental results can provide the technology reference for the optimization of abrasive flow machining theories,and offer the guiding significance for determination of the optimal technology plan of abrasive flow machining non-linear tube parts.
