摘要

In this study, an ultrafine WEDM (wire electrical discharge machining) of micro-channel mold is proposed. It could be divided into two parts, rough machining and finish processing. In rough machining procedure, high machining voltage is adopted to improve machining efficiency. In finish machining procedure, extended and trimmed tool path is adopted to obtain the cusp at the corner, low electrical parameters is adopted to improve surface quality and dimensional precision. By conducting finish machining of 40V, a better surface-quality with Ra of 0.32μm and high aspect ratio of 20:1 was fabricated.
