Cutting Conditions for Fanuc F0-3015 Laser
(OP)
I have been running a Fanuc F0-3015 Laser with a 4000 laser and I can't seem to get HRS0.500 material to cut smooth edges like my HRS0.375 material. I was wondering if any one had some baseline cutting conditions for this material. I have been using a NON WAC and a 7" focal length. Any suggestions will be greatly appreciated.I believe this is a mild steel.

E4 35"/MIN 4000W 2000HZ 100 DUTY GAS 0.08 NOZZLE GAP .030"
FOCAL POINT -.075" 7.5" LENS, 1.4MM DOUBLE NOZZLE.
Our focal point is negative because our NC is an older model,(Fanuc 160i-l series). I am able to cut better however the edge is still rough and sometimes it randomly doesn't finish cutting a hole all the way. We are scheduled for a turbo repair and also optics. Could it be our optics and turbo have something to do with our cut conditions? Is there some other adjustments we could use?
Thanks Again

If the cut is still rough, try to lower the gas pressure as low as you can without losing the cut; the lower it is, the smoother is gets. If that doesn't help, play with focus; I would try higher first; go by increments of 0.02" (0.5mm).
If that still doesn't cut good, could be something going on with the beam, or maybe material specs.
Were you able to cut that same material with good quality in the past?

To add to what Footstrap said about frequency and duty: Use a larger nozzle (2.5 double) and use edge and approach data as needed. Maybe even WACS. Increase/decrease your focus by 1 mm on a 7.5" lens otherwise you'll barely see changes with .5 MM, that I would do on a 5" Lens.
Sometimes it's not worth fighting the material quality and it's more important to get parts out the door. You'll likely succeed by lowering the power, feedrate and using a larger diameter nozzle.

The way I try to explain it is, the cutting window is very small, not forgiving at all. What the previous post suggests, is breaking out a larger diameter nozzle and making the cutting window bigger, more lee-way on the other settings.
I agree the WACS set up is a pain. You don't have to use this cutting head when you go with the bigger nozzle diameter. Use the WACS cutting condition just turn the water "off" and it should work out well.
To answer some of your other questions: new discharge tubes shouldn't effect the laser one way or the other. If they are installed properly and the machine is aged and purged completely, you should not see a change in cutting.
The standard Amada and Fanuc procedure when changing out a turbo is to put the turbo in, purge and age the laser to get it back to where it was before the procedure then wait a few weeks or a month and then replace the internal optics. During this time its possible the cut quality to decrease. The best indicator that there is a change is to keep and eye on the Laser Calibration Coefficient, Parameter 15204

Thanks so much

As far as not having the nozzles, I would take a 1.4 Eco Nozzle and ream it to 2.5 until you get the new ones and try it. Not the best way to go about it, you'd rather have a near perfect concentric nozzle but you gotta do what you gotta do to get the job done.
Good Luck

Good luck.

On a different note I was wondering how to get my .500 material pierce point to cut cleanly. At the present it appears to be allowing a patch of slag to bubble out and when the head hits it the head bounces and it doesn't cut completely through. I have set my pierce settings according to the Amada material list book and I did increase my approach from .1 to .23 in my drawing and that helped at least I am not having to scrap or clean up as much material. Again I want to thanks all you guys for the help.
