Development of a method for performance characterisation of PEMEC process considering electrolyte temperature in case of hybrid polishing of 316L steel

Abstract

Abstract. This work falls within the context of very rough parts (Ra > 10 µm) polishing using a new hybrid process called PEMEC, which combines a mechanical abrasion action (tribofinishing) and an anodic dissolution action (electrochemical polishing). The study of the performances of a polishing process requires the monitoring of the surface roughness, but also the monitoring of the dimensions and the shape of the parts. This paper proposes a new method for characterising polishing operations that enables all these criteria to be monitored in a single test. This method is applied to the study of the influence of the electrolyte temperature in the PEMEC process.
