EDM or EDM Machining?

"ATM Machine" as well, for all the bankers out there.

.......... and what's up with "tuna fish" thing?

Don't forget CRT tube.

OOPs, shows my age.

There are a few acronyms of which is used EDM. The use of the word machining clarifies which one.

It is important to have at least one mistake in every document so the reviewers have something to correct. This rule makes "EDM machining" (Electrical Discharge Machining Machining) very important. Without something trivial like this a reviewer would have to resort to messing up something important.

Actually the redundancy is for clarity. 'EDM machine' is noun for the electrical discharge machining machine; 'EDM Machining' is a noun (I bet it s what bulah jerles taught me was a 'gerund') that describes the process of using an EDM Machine to machine something.

SO the redundant term provides intent and context. Despite the strict constructionists policing the language, fact is Language is a tool, and it is often used for best effect rather than to achieve linguistic orthodoxy.

I'm reformed. I'm sticking to taxonomic topography.

In the shop we would just say EDM. We all understood that it's a machine.

It's the outsiders that muck up the terminology.

Have to agree with Hooker. Go to any tooling/machine shop and say EDM and you need to say no more. Maybe plug or wire, but everyone understands that it's a machine that removes metal using electricity.

Hi Paddy O'Flanigan,

Like EDM Machining, ECM Machining ( Electro Chemical Machining ) is also being used in our shops. ECM Deburring & ECM Polishing are some more processes in the same way being used.

Electrical Discharge Machining - Machining.....its connected to a hot water - heater.....which makes it really, really hot before it passes through the cold water heater.

I'd appreciate feedback from the machining and fabrication sector out there as to which is the more appropriate term.

The terms Erosion Machining, Wire EDM, Ram EDM and Sinker EDM won't get you laughed at.

Let us not forget "Smiling BOB" and his definition of EDM if we are to be humerous.

The gramatically correct statement would be EDM without the "Machining" repeat. we do this a lot in our world.

normaly we the technical people use the term / letters EDM to name both the machine and the process of EMD-ing. we tell EDM it.... or EDM the job. In most of the countries people use the word Sparking to name the process of EDM. in some regions like Europe .... people say Errotion.

but mostly the non-technical people only use one more Machining behind EDM. ie. EDM Machining.

Hay Guys,

I've seen a problem in EDM. when ever we spark a large area, say 150 x 250mm, on which there are some blint holes, after a while working, the electrod stop removing matirial fron the job and it just keeps moovine up n down. how to overcome such problems.

thanks in advace for your valuble ideas.

Back in my day of EDM ('70's), this usually resulted from inadequate removal of spark residue. Depending on the job, we made sure we had a constant flow of electrolyte through the spark area to keep a clean arcing surface between the face of the electrode and the work piece, otherwise the machine would "hunt" for a valid area.

The larger the burning surface area the greater the problem. Also the depth of the hole/area can contribute to the problem if it's a blind hole. Pre-conventional machining is often necessary or desired to minimize the problem. Rough machining on a mill really cuts down on EDM time.

Lastly, change the fluid/filters on a regular basis.
