Abstract: Abrasive Flow machining is a precisely controlled and repeated method of material removal which is used to deburr; polish and radius difficult to reach. In Electrochemical aided abrasive flow machining a polymeric electrolyte is added to the prepared media. It is a hybrid process of Electrochemical Machining (ECM) and Abrasive Flow Machining (AFM). The key components of ECA2FM process are the machine; tooling; voltage regulator and abrasive medium. One serious limitation of this process is its low productivity in terms of rate of improvement in surface roughness. In the present work; the intensified machining action has been observed due to the cooperation between AFM and ECM processes.
