ステンレス鋼の電解研磨加工における加工条件の最適化

抄録

Electro-polishing is a process having a merit of being able to obtain a smooth surface. In the process, it is necessary to adjust the processing conditions depending on the shape. But few reports have been published on the effects of processing conditions, which are mostly determined by experience.

In this study, an electro-polishing process was optimized for austenitic stainless steel using the Quality Engineering approach. From the results it was clarified that the factors including polishing voltage, anode surface, anode surface diameter and polishing solution flaw significantly affect SN ratio and sensitivity. Under the optimum condition, it became possible to continue working without being affected by the deterioration of the polishing solution.
