Titel
Edge rounding of EDM micro bores using a plasma electrolytic polishing process
Abstract
Micro bores are an essential element in numerous technologically advanced parts. The micro EDM process can deliver small diameter bores of high accuracy, but due to its process principle the resulting bore edges are sharp. For fluidic applications, a round bore edge is advantageous, whereas the rough bore wall structure is ideally to be preserved. Conventional, e.g. fluidic grinding processes, can not separate the both. Here, an investigation into the usability of the plasma electrolytic polishing process for a selective edge rounding and surface smoothing without affecting the inner bore wall is presented. Using suitable parameter sets, a novel approach can be delivered.
