Synopsis:

Electrochemical assisted abrasive flow finishing is a newly developed hybrid finishing process which is used to finish the internal parts of work piece having complicated geometry to a large extent. In electrochemical assisted abrasive flow machining higher abrasion of the material was detected due to the combined effect of ECM(Electro Chemical Machining) and AFF (Abrasive Flow Finishing) processes. In Electrochemical aided abrasive flow machining, a electrolyte is added to the prepared media .This media consist of a kind of polymeric carrier and abrasive particles that are hydrocarbon gel, Al O , Silicon based polymer, and NaI (Sodium iodide) as electrolytic salt. In this experimental 2 3 research, different process parameters such as voltage, abrasive concentration, number of cycles, molal concentration and diameter of rod were considered at different levels for response characteristic of surface roughness (Ra) based on Taguchi method using standard L27 Orthogonal Array (OA) for the plan of experimentation. To determine the contribution of each parameter, analysis of variance was used.
