Composite Tools Design for Electrolytic Magnetic Abrasive Finishing Process with FEM

Abstract

In hybrid process of electrolytic magnetic abrasive finishing (EMAF), there are usually two structures on the tool design, separated or composited. This paper has been focused on the design of the composite tool. How to make electrolyte reach working area is a problem which should be solved for the EMAF process when the composite tool is used, therefore a hollow structure of magnetic pole has been put forward as one possible solution. To understand the effects of the structure parameters of the tool on the abrasive brush of EMAF, Finite Element Method (FEM) has been employed to establish the magnetic field model and analyze the distribution of magnetic induction on the workpiece surface and magnetic pole.
