Help with cutting parameters
Help with cutting parameters
(OP)
I bought a used Amada LC-2415 alfa III NT. (2kW)
I have no prior experience with laser cutting machines but i'm a fast learner.
2 weeks ago I finally finished the installation and the Amada technician here in Israel came and did all the necessary procedures to turn the machine ON.
For the last two weeks i've been cutting material 8 hours a day.
I have cut:
Plain steel 1mm-10mm
SS316 1mm-6mm
Alu 1050 1mm-2mm
Many of the materials were not on the machines cutting list and I had to find the right parameters to make the cut work.
I know it can cut much better than my "make it work" adjustments.
I did get a user manual but I did not get a cutting list manual.
I found it very difficult to understand the user manual because it doesn't really say much about how each parameter effects the cutting quality.
I did an intensive search and found a great book that was published here in this forum "Cutting know-how for amada lasers"
This was a good starting point but still I'm lacking the understanding of how the Edge, Fine Edge and such features work and effect the cut.
Everything about lenses is still a mystery to me, and i have no idea when to use the 5" and when to switch to 7.5" other than what it says on the already defined materials.
Here is my question -
Where can I get the cutting list parameters book for my laser?
Where can I find good literature on all the cutting functions and the effect they have?

Good luck

Laserdog, actually I have a user manual but what i'm lacking is the cut tables with all the different materials and parameters that goes with them.
If you have this table/book ( i have no idea in what format it came) I will be more then happy to make me a copy.

THANKS
I'm looking for the "Jumping for joy" smiley, and can't seem to find it :)
Any other notes will be equality appreciated

If it interests you I can send you the cutting conditions tomorrow

It took me several hours and more then 30 pcs of trial cuts to achieve a really clean cut.
All those testing were done when the machine was only a few days old, and I had no idea how and what should I change to make it work.
Tomorrow I am starting a new job with many sheets of 6mm stainless, My guess it will take me several days to complete.
Before I start, I will try to rework on my settings with your recommendation about the power/freq.
When changing cutting type between "clean" and "thickness" what changes?

RE: Help with cutting parameters
I started the morning with 4 hours of trials to set up new parameters.
Ended up with something not as good as I had but a bit faster 700cm/min instead of 500cm/min.
Tried my old settings again, and it did not cut as clean as it did on the first time
Nitrogen pressure is 0.85Mpa, in just 4 hours I drained 12 cylinders.
And still got a black cut and burr.
How can I make it cut better?

M103B0.05 pierce
This is 3/8 stainless (.375)
RE: Help with cutting parameters
Always thought: if it goes all the way thru - its good enough.
I will take some pictures of my pierce (only tomorrow) but from what i remember its quiet with sparks going in all directions for about 3-4 sec.
Even if the pierce is good (or bad) why will it effect the whole part?
Parts i'm currently working on are very large, I only have 4-5 pierces in a sheet.
I do not know what M103 or M103B.05, where do I set this parameter?

Attached are the new pierce condition 103
And a sample cut with this pierce
But that does not solve the black cutting surface.
I am trying to think outside of the box, maybe the nitrogen isn't clean enough.
I'm using a 99.99% pure nitrogen with O2<50ppm.
Is that ok?
when cutting a circle, i get no burr, but when cutting straight lines i get burr on one side of the cut
Another annoying effect is black splatter under the sheet, which can be seen in the attached picture
RE: Help with cutting parameters
1. Change the nozzle gap to .5
2. Change the focus to -4
3. Cut a part
4. Change the focus to -7
5. Cut a part
6. Compare the 2 so we have a better idea with the focus

problem solved, tell you all about it later today.
RE: Help with cutting parameters
After 4 hours with no luck, I had to do something, I had to start cutting.
So, I did.
The cuts came out black with sharp burr and all dirty with splatter.
But at least I made the cut.
So today (friday) I went back to work, and tried to adjust the parameters to make the cut clean and shine.
Again I spent 3 hours in the morning with no luck.
Afternoon I saw laserdog was asking about focus point, So I had back to work turned the machine ON and started cutting sample circles with different focus points. (at -8.5 the laser could not cut)
After the 3rd circle my nitrogen run out. just when I found that the best focus is going to be at -6.5.
I thought about closing everything and head back home to my family, but then decided to give it another try with the nitrogen cylinder from the dust collector.
How surprised was I when I changed nothing in the parameters but the cut came out beautiful.
Only then I realised that my nitrogen 12 pack are not as clean as they should have been.
I tried cutting rectangular and one side had a little black burr underneath.
I boost up the nitrogen pressure from 0.7 to 0.8 Mpa and the burr was gone.

For the edge any approach data I'm using 203 an for pierce I'm using 103. The lead in length is 0.150" add Im using a micro tab of 0.05"
RE: Help with cutting parameters
101 pierce power 3000, freq 15, duty 15, Incr freq 5, Incr duty 1, step count 1, pierce time 5.
103 pierce power 4000, freq 100, duty 100, Incr freq 0, Incr duty 0, step count 0, pierce time 3.
