I have been making electrodes for years but in the past two months I have taken over the Sinker EDM as well. So I'm pretty new. We have a Mitsubishi EA28V.
Usually we make three electrodes per feature being burned. Somewhere in the range of 18 to 24 VDI for the finish. If I am looking to get a more crisp corner on a tight feature we sometimes make a 4th electrode to get that last little bit.
My question is, when I am using 4 electrodes, is it best practice to tell the EDM that I am using 4, and let it figure out the power settings for each one. Or should I program it as 3 and use that last electrode at the identical power settings as #3. So its just a redundant trode to get any remaining stock.
