ELECTRODE MATERIAL EFFECT On CNC EDM, Part 2: A discussion of the reasons why the use of more, economical electrode material is not always the most cost-efficient means of CNC EDM

摘要

All too often, an EDM is purchased on the premise that optimum performance will be realized regardless of the electrode material used. Part one of this article (March 2010) introduced the effect that the electrode material can have on the adaptive control of a CNC sinker. This article will describe the details of a test conducted with an identical rib detail machined from materials of two different classifications and programmed to complete the same task.
