Anybody familiar with ECM, or Electro-Chemical Machining?

<< < (4/4)

ddmckee54:
I spent some time with my friend Google last night.  In found a couple of interesting research papers on Electro-chemical Jet Machining.  One was investigating cutting a Japanese grade of 304 stainless, SUS304. I THINK the other was looking at cutting an aluminum/titanium/boron alloy, TiB7050?

Being good research papers they both listed the parameters used in their experiments.  I was particularly interested in the differences between their single pass cuts in the two materials.  A single pass on the SS only cut about 20-30 microns deep with a feed rate of less than 1mm/minute.  The aluminum alloy on the other hand was a whole 'nuther ball game, a single pass cut about 600 microns deep with a feed rate of 30mm/minute.  The author of that paper remarked that you could practically see the excavated material being conveyed away.

I haven't found anything on cutting a more normal steel yet, although I did see a video of ECM being used to rifle pistol barrels.  The entire rifling  process, from cycle start to complete, took less than a minute.
