How Sinker/Ram EDM Works: Part 1

Carl Sommer, president of Reliable EDM, shows how ram, sinker, or plunge EDM works. He describes the sparking process, how the electrode erodes materials by means of spark erosion, and what transpires inside the cut. He also speaks about the power supply, servo mechanism, chiller, filter, C-axis, and the various angles ram machines can cut.
Sommer, president of the largest EDM job shop in North America, has also co-authored with his son Steve, a mechanical engineer, Complete EDM Handbook. The handbook is free at their website.
