Electrochemical magnetic abrasive machining of AISI304 stainless steel tubes

摘要

This work presents the characteristics of advanced abrasion based hybrid machining process consisting of electrochemical dissolution and magnetic abrasive machining process. The cylindrical electrochemical magnetic abrasive machining (C-EMAM) setup was developed and mounted as an attachment on lathe for high efficiency machining of cylindrical jobs. Experiments were conducted to explore the performance of the process on AISI-304 stainless steel tubes using unbonded magnetic abrasives. The effect of various process parameters viz. rotational speed of the workpiece, current to the electromagnet, electrolytic current and frequency of vibration on material removal and surface roughness were investigated. The electrochemical process has major contribution in material removal, whereas magnetic abrasive machining helps in reduction in surface roughness. This process has higher machining efficiency particularly at high value of electrolytic current and high rotational speed.
