.500 Steel on AMADA FO3015?????

.500 Steel on AMADA FO3015?????

.500 Steel on AMADA FO3015?????

(OP)
can anyone help me out with cutting conditions for .500 steel im having a hard time getting a clean cut????????
Thank yallafro

RE: .500 Steel on AMADA FO3015?????

(OP)
im all good now my pierce was my main problem but I cant seem to erase this post, thanks yall

RE: .500 Steel on AMADA FO3015?????

What settings did you land on exactly? I am running the same laser and have major issues every time I get a 1/2" job.

Thanks

RE: .500 Steel on AMADA FO3015?????

Your getting a lot of heat build up there Fabpro. I'd say you need to increase your assist gas and lower the feed rate a bit. It's just a matter of getting a scrap piece and dialing in what works foor your machine. Cause what works on LaserSpyder's machine may differ from yours. You don't look to far off where you need to be.

If you ask me to do something, I will do it. There's no need to nag me every 6 months

RE: .500 Steel on AMADA FO3015?????

Looks more like a nozzle alignment issue to me the heat is all on one side of the piece. I always use the smallest nozzle available to do my beam alignment when cutting mild steel

RE: .500 Steel on AMADA FO3015?????

(OP)
FabPro id say ur pierce is wrong try pierce M103A7 and ill post my cutting condition in just a min

RE: .500 Steel on AMADA FO3015?????

I don't think nozzle centering is the issue but it of course should always be checked when having troubles.

Looks to me like it is getting too hot. Also the nozzle might be pulling away from the work, changing the focus. This sometimes happens as a product of other parameters being off. If anything the feed rate may be too slow, causing the excessive heat.

We can be far more helpful if you share your current parameters. Do you have an additional lens you can try to eliminate it as a problem?

RE: .500 Steel on AMADA FO3015?????

Jetrep - I did try a brand new lens and got the exact same result.

I am currently cutting at about 43 in/min.

I created a new grid for that part that skips around the sheet to keep from getting too hot, which has worked in the past. But without the first few parts cutting well, I can't rely on the grid to do anything other than mess up a bunch of good material.


Laserspyder - When you use the woodpecker pierce (A7) how many pierces or "zaps" for lack of a better word do you use?


I will take a picture and post the current parameters soon.

RE: .500 Steel on AMADA FO3015?????

(OP)
are you using E003 for ur inner cuts/holes? if so they shouldn't be too different then ur E004 outer cuts

RE: .500 Steel on AMADA FO3015?????

LaserSpyder - Disregard the other cut conditions. Currently only using E4 for these parts. I started from scratch this time around playing with the settings. What you are seeing is a copy from one of my other cut conditions for thinner material

RE: .500 Steel on AMADA FO3015?????

Your nozzle gap at .060" seems high. Our documentation suggests .030"

The parameters I have straight from Amada for an Fo3015NT 4kW laser:
55"/min (I'd stick with 40"/min for now)
4000 watts
2000Hz freq
100% duty
.08 gas
.030 nozzle gap
.040" focus

RE: .500 Steel on AMADA FO3015?????

Jetrep - I will give those settings a go tomorrow. I had raised the nozzle gap based on responses in another thread.

If what was being said earlier about the cut from @thelaserburns was true, "Looks like too much heat"

--Increasing to 4kw , 2000 Hz, and 100% duty would in fact increase the amount of heat being put into the material?




This is also extremely weird. I will post a picture in the AM, but I had sheared off the used portion of the sheet and the cut looks almost perfect.

RE: .500 Steel on AMADA FO3015?????

I was simply sharing the info I have from my Amada notes. I don't know how much success you may have with those settings. Your straight cut looks decent but straight cuts are easier than more realistic features where the effective feed rate is constantly changing and approach data is changing things in corners.

Having the nozzle gap that large makes the head a bit more likely to rise further from the sheet. once that happens it doesn't typically come back down and your cut goes bad or it loses the cut all together.

RE: .500 Steel on AMADA FO3015?????

(OP)
my cutting conditions are .....FEED RATE.40. POWER.3700 FREQ.1500 DUTY.100 GAS PRESS.0.10 GAS tIME.2.0 NOZZLE GAP.0.0300 FOCAL INCH-0.098
and my material info is set to STD
these should get you at least going in the right direction hope it helps 2thumbsup

RE: .500 Steel on AMADA FO3015?????

(OP)
and I cut my .250 like butter beautiful cuts if u ever need those Hollarnoevil

RE: .500 Steel on AMADA FO3015?????

Sorry to intrude, but being this side of the pond. What conversion would you use when your feedrate is .40 for example. On my parameters I have feed rates of 3000, 4000 for example.

RE: .500 Steel on AMADA FO3015?????

(OP)
evans I think ur in MM so 40 in ur measurement would be 1016 I think I would double check that but u can probably compare and confirm morning

RE: .500 Steel on AMADA FO3015?????

if your feed rate is .40, wouldn't that be meters per min?

Evans - 25.4 mm = 1 inch

RE: .500 Steel on AMADA FO3015?????

-LaserSpyder - after digging into my laser a little bit more i realized there was a larger problem then my cut conditions. My A/O mirror was not adjusting when it needed too. Now we are currently replacing the Air pressure regulator for the A/O.

On a side note - how fast are you able to cut 1/4" like butter?

RE: .500 Steel on AMADA FO3015?????

(OP)
FabProHelp that should make a huge difference in cut, and my cut conditions for .250 steel are ....
FR 90. PWR 3600 FREQ 1000 Duty 90% GAS P. 0.07 GAS TIme 0.5 GAP .040........how does ur .250 cut?

RE: .500 Steel on AMADA FO3015?????

Before we replaced the Air pressure regulator, my 1/4" was cutting amazing but I had my feed rate down to 60 in/min. Just started to re-adjust the settings now and they cut clean at 78 in/min. I am going to try ramping them up to your settings and see if I can get closer to 90 in/min.

I will keep you updated.... hopefully this corrects my 1/2" cutting issue

RE: .500 Steel on AMADA FO3015?????

LaserSpyder - How deep do you have to drive your focus to cut that quickly?

RE: .500 Steel on AMADA FO3015?????

(OP)
my focus (focal(inch)) is set to -0.031 sorry I meant to put that in but didn't laser

RE: .500 Steel on AMADA FO3015?????

(OP)
FabProHelp we recently replace our (NC programmable assist gas regulator" p/n 71359715 NC regulator) ......... and OH MAN did our cuts IMPROVE! our 190Alum is cutting better then ever and that was our #1 problematic material and thickness, and we never even suspected there was anything wrong with our assist gasses.machinegun

RE: .500 Steel on AMADA FO3015?????

What do you consider to be the max thickness you cut on your FO3015? Steel - Aluminum - Stainless Steel

RE: .500 Steel on AMADA FO3015?????

I don't cut steel but aluminum I can cut .375 and stainless I cut 1.000" with my fo3015 4kw resonator

RE: .500 Steel on AMADA FO3015?????

(OP)
.5 inch is the max ive cut

RE: .500 Steel on AMADA FO3015?????

here's some pics of 1" stainless on my 4kw

RE: .500 Steel on AMADA FO3015?????

RE: .500 Steel on AMADA FO3015?????

(OP)
now I want to cut some 1" deejay ..... I bet u can clean those cuts up a bit with your gas pressure and driving focus down a little deeper I think anywho machinegun

RE: .500 Steel on AMADA FO3015?????

The pierce is the hard part and I only get 17 bar out of my machine.

RE: .500 Steel on AMADA FO3015?????

(OP)
you using Nitro?

RE: .500 Steel on AMADA FO3015?????

Yes but o2 for pierce

RE: .500 Steel on AMADA FO3015?????

I'm looking for some inner cut conditions for 3/4" carbon steel. I can cut the perimeter great, can't cut holes .500". Terrible.
My focus is at .142. I see posts where the focus numbers are low.

RE: .500 Steel on AMADA FO3015?????

(OP)
Laser Lozer can u post a pic of ur cut conditions?
