First things first, I'm totally green on an EDM. Picked up the manual to our new Agie CUT 350E last Friday and by the end of the day was able to cut out a 2D shape of my own design out of 20mm steel using the tech files that shipped with the machine.
Now I have some parts that I need to make out of thin (1.5mm) brass but I'm running into a few problems:
1. There isn't a brass-specific tech file on the machine already (I have steel, copper, aluminum, hard metals, and titanium)).
2. There isn't tech information for any material under 10mm thick.
3. When I try to get around these problems by stacking parts up to 10mm thick and using "copper" tech to run the cut, but the wire breaks after 10-15s of cutting. The part that cut before the wire broke looks OK.
What would you guys do in my situation?
Is there a better material to use for the tech than copper when cutting brass?
How do you deal with cutting thin materials or developing a tech for them?
Any chance anybody has compatible tech files for thin brass in a 350e?
And one broader question: what parameters do you normally start tweaking when you adjust a tech file? There are so many that it's overwhelming vs. a conventional machining op like milling or turning.
Here's some more detail around what I'm using:
Agie CUT350e, under 10 hours on it and just installed by the factory tech two weeks ago
Agie Brass wire, Ø0.25
Workpiece is 360 brass
I have good flushing, with upper/lower cones <0.2mm from the part
Thanks in advance for any help!
