Study of Process Characteristics of Abrasive Flow Machining (AFM) for Ti-6Al-4V and Validation with Process Model

Abstract:

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 finishing 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 Ø20mmID cylinder although the theoretical plots show over prediction in some conditions.
