Enhancement of Surface Integrity using Spark Assisted Abrasive Flow Machining Process

In today’s competitive environment components havin g high dimensional accuracy and better functional performance are highly demanded. Abrasive Flow Machini ng is one of the vital non-conventional techniques u ed for the finishing of complex geometries which is not eas y with other conventional processes. It provides fin ishing up to nano level. During the finishing, parameters affecting t he system efficiency are very important to identify to improve the productivity of the system. This paper discusses a newly developed technique i.e spark assisted Abrasive Flow machining, which uses the spark energy to improve the material emoval and providing better surface finish and als o parameters such as rotational speed of the electrode, duty cyc le and current were optimized for the better surface finish using Taguchi L9 OA.
