ABSTRACT—Advanced Abrasive Flow Machining (AAFM) is described and case-histories are
presented that show how this automated die polishing can improve the productivity and quality in
extrusion plants, when it is applied to both new dies, and those being re-polished between runs.
Improvements in media and process control strategies are discussed, and how they affect the
performance, life, and repeatability of dies. Examples that compare the traditional approaches with
this new method are shown, including the resultant improved die life, profile quality, and profile
