need cut conditions for mild steel
(OP)
could somebody send me cut conditions for mild steel we generally cut ss and my cut conditions are fine but mld steel cuts very bad with existing conditions. machine type is Amada FO3015 with 4kw resonator. any help would be greatly appreciated.

you might have to slow the feed rate a bit. We have had some success getting nicer edge quality with gas pressure set to 0.10
RE: need cut conditions for mild steel
A couple of things to consider also would be the quality of the material you are cutting. This makes a huge difference.
By the way, once you set the duty cycles to 100% the frequency is ignored because you are now cuting with Continous Wave (CW).

11 Ga you could use the same set-up but instead the gas pressure should be lowered to .15 and speed to about 140"/min.
I guess my only question to you would be: Have you done a focus test on your lenses or you just put them in when you replace them with a new?

Do understand also that Fanuc is mainly a control, drives, and robotics company and not a laser company like Trumpf that invests heavily in R&D for laser where it makes its money. One great thing about the Fanuc though is its reliability and despite the larger beam diameter it can still cut a wide variety of materials. It just won't cut as fast as say the Trumpf or Bystronic Resonator. One of the good things about it are its modular power supplies that generate the high voltage, something Trumpf doesn't have and instead uses the RF Tube that can cost a pretty penny. Not that this is bad, it's just a different method.
I must say that it's easier to transition from a Japanese machine to a European machine than vice-versa. You are just getting to learn the machine and with time you'll do just fine.
RE: need cut conditions for mild steel
I believe the previous comments about beam diameter in the system (upstream of the lens) are totally backwards.
There are several reasons to want a large beam going into the lens:
1. you can get a tighter focused spot for a given lens focus length
2. you can get a longer beam waist for any given spot size ?
3. less beam intensity on the lens surfaces. (though maybe the longer path from center to edge nullifies this?)
At least, these were my understandings while at Amada.
Is this no longer the case?
