| Abstract | The objective of this study is to improve production rate for bio-medical devices stainless tube. In particular, attention is focused on parameters of the electro-etching procedure into the manufacturing process for stainless wire. The wire is used for angiography or arteriography that is a medical imaging technique used to visualize the inside, or lumen, of blood vessels and organs of the body, with particular interest in the arteries, veins, and the heart chambers, so quality of work is important. Electrolytic etching is technique which gives fine, bright and stress-free surface. This paper reports the findings of an experimental investigation on Electrolytic etching of SUS304 stainless steel. In this investigation, effect of process parameters on performance measure as diameter reduction rate was studied. The process parameters which were chosen were: current (A) and electrolysis time (min.). The relation between current and material removal was proposed. The results and the significance of controlling parameters were analyzed using analysis of variance (ANOVA). It was found that current is a significant parameter. The electrolysis time and the number of workpiece for each lot sizes were investigated. |
