Abstract

Abrasive flow machining (AFM) is a process for finish machining of edges and surfaces by the controlled extrusion of an abrasive laden viscoelastic polymer across these edges or surfaces.

Since the initial development of the process in the mid-1960’s, to deburr hydraulic control blocks used in the radar-guided target acquisition systems for Phantom Jets, the process has gained widespread acceptance across the broad spectrum of modern manufacturing industry. Applications now range from high technology aerospace components to high volume automotive components [1].

The Authors are currently involved in an extensive research and development programme into the abrasive flow machining (AFM) process. The aim of the research programme is to achieve a better understanding of the the thermal and fluid flow properties of polymers used in AFM, in order to establish a basis for the control and optimisation of the process.

The results reported here include the rheological characteristics of the Extrude Hone MV polyborosiloxane material, a description of the AFM process and consideration of the relationship between these rheological properties and the process.
