Study of process characteristics of Abrasive flow machining (AFM) for Ti-6Al-4V and validation with process model

摘要

The aerospace components made of titanium alloy with internal passages have complex geometries and their surface smoothness play an important role on the improvement of fuel efficiency.Hence,a surface fmishing method that can produce a conforming surface finish to all internal surface features is required.This paper studies the process characteristics of AFM for Ti-6Al-4V experimentally.In addition,validation of process model based on the tribological interaction between AFM media and Ti-6Al-4V with empirical data is carried out.The theoretical plots agreed well with experimental results on (O)20mmID cylinder although the theoretical plots show over prediction in some conditions.
