The aim of the study is to investigate the micro-finish and flatness of the flat functional surfaces made of stainless steel (SS321) using a newly developed electrochemical honing (ECH) machine. ECH is a prominent hybrid machining process (HMP), which is widely used for precision finishing of intricate shapes and hard materials with an efficient and effective manner. In the present work, flat work surface is processed through ECH and pressing time dependent behavior of ECH has been studied. The results show that the ECH of SS321 surfaces gives a glazed appearance and produce an average surface roughness (Ra) of 0.84 μm, and flatness in the range of 5-12 μm with a processing time of 360 seconds. The analysis of finished surface through 3D optical profilometry images has shown improvement in the surface integrity of the workpiece. The microscopic analysis showed that the ECH processed surface is free of burr and scratches.

Abstract


The aim of the study is to investigate the micro-finish and flatness of the flat functional surfaces made of stainless steel (SS321) using a newly developed electrochemical honing (ECH) machine. ECH is a prominent hybrid machining process (HMP), which is widely used for precision finishing of intricate shapes and hard materials with an efficient and effective manner. In the present work, flat work surface is processed through ECH and pressing time dependent behavior of ECH has been studied. The results show that the ECH of SS321 surfaces gives a glazed appearance and produce an average surface roughness (Ra) of 0.84 μm, and flatness in the range of 5-12 μm with a processing time of 360 seconds. The analysis of finished surface through 3D optical profilometry images has shown improvement in the surface integrity of the workpiece. The microscopic analysis showed that the ECH processed surface is free of burr and scratches.
