automatic decontamination

[nidbe]

please i want to know how the automatic decontamination in the machine AMADA fo 3015 (Fanuc Series 160i-l)

?
what is this automatic decontamination you speak of?

from Google, I see references to coatings removal and such.
also scarier things, like decontaminating surfaces that have radioactive contamination.

Do you want to do that with your machine?

ok, it sounds like the laser "sees" some form of contamination on gas change, and goes through a purge and burn sequence to clean the cavity.

How clean or nasty is the environment where the gas bottle is?
Could you be getting contamination into the regulator when you make the change?
(what kind of chemicals could be in the area, or in the air?
Is the new bottle nice and clean when you connect it up?

Have you asked Amada about this? Do others in your area have good success with that gas supplier?

Do you mean that it's going through an aging cycle (AGING flashing in the lower right of the screen), or is it only going though calibration (sequence 28)?
Maybe your calibration time is set too high; check parameter 15205 (calibration time in seconds; usually from 180 to 300 depending on resonator type).

[highlight #3465A4]thank you all for your help ca'm happy to find people like you ... I am from north africa ... and I'm a bit new to the field of laser cutting ....

the machine parameter 15204= 1346 and it is not stable in each reset ...[/highlight]

1346 is extremely high for param 15204. This means the measured power is way down. Make sure your laser gas specs are correct (not all Fanuc resonators use the same gas specs). Eventually try another laser gas bottle. Make sure you don't have any internal and external leaks. Make sure there are no cooling issues.
Other than that, next, it could be the power sensor that is bad, or your internal optics are due for a replacement. How many hours do you have on the internal optics?

 

[nidbe]

the internal optics are changed 3 months back

Once the resonator is at sequence 30 (and not cutting, just sitting there), also check the voltage of each power supply. Compare to the values in the Fanuc datasheet (which should come with the resonator; if you don't have them, contact your machine supplier). If voltage is way off, your laser gas is probably bad.
