EDM Wire feedrate

[DaveJ-FTM]

Good morning gents,
This is my first post and hopfully I placed this in the correct catagory. What I'm hoping to get is just a general idea on what type of feed rate (IPM) can a wire EDM typically achieve in hardened 17-4 PH that is 1" thick. I realize that there are many many variables that influence this but hope that if I can provide enough of the "knowns", you can at least give me a some sort of ballpark range in feeds (IPM) based on your experience.
Please understand that I'm not looking for perfection and I abosultely don't want you to waste your time creating a manuscript identifying all the unknowns. Even a "gut feel" will work for me for this application.

Material: 1" x 2" x 3" hardened to 45Rc. The wire will run through the 1".
Linier inches: Aprox 15 linier inches of EDMing is required.
Wire Dia: .010
Tolerance: +/- .001 (pretty open)
Surface Finish: 63 or better.


Thanks again for your help.

My old charmilles andrew might do 3" per hour. I'd probably leave it run slower.

Thanks Karl. I appreciate your feed back. As of now, I at least have some idea of what is possible.

you should be able to get anywhere from.100"/minute to .200"/minute
if you are using brass wire,the feed will be on the lower side,for zinc coated wire it will be on the higher side,you may even be able to go higher than .200"
