More LC1212 questions
(OP)
We are now cutting mild steel hot rolled plate. We got the peirce figured out as it is good only the corners are an issue now. Most corners are good but too often they get overcut when coming out of the corner. Could anyone tell me what paramter in the edge conditions make the most difference and what it should be for example 1/4 plate.
Thanks for any responces, just found this forum and it has helped already.
As far as tech advice from Amada, we bought the machine new from them and tech calls do not get returned.

RE: More LC1212 questions
another problem I have encountered that messes up the corner is that if you switch cutting conditions at the corner to fix the messed up edge you can also mwss up your offsets and your part will vary in size at opposit ends
I hope that helps
RE: More LC1212 questions
Edge Control will solve this problem by stopping in the corner and pulsing for a certain distance.
Go to your Edge Data Screen and use the following:
Work Angle: 90
Pierce Power= 0
Pierce Duty= 0
Gas Kind: Same as cutting condition
Pierce Gas Pressure: Same as cutting condition
Pierce Time= 0
Distance= 0.059"
Vor Rate= 3.5"
Vor Freq= 10 to 25 Hz
Vor Duty= 25 to 30
Hope this helps

RE: More LC1212 questions
I have read your posts about using the "edge data" screen to pulse cut around corners before.
Is this method equivalent to "power ramping" on a Mazak?
I have used corner looping in the past but I am interested in trying the power ramping. Would you suggest one method over another?
Thanks and I really appreciate your posts on this forum!
RE: More LC1212 questions
Similar concept but different.
Power ramping is known as Dynamic Power Control (Cincinnati), Modulation (Bystronic), Fine Edge Control (Amada), etc. This function works when there is a change of speed in the machine. Acceleration power ramps up, deceleration power ramps down. This is mostly used in thin gauge materials.
Edge Control (Amada)is a function mainly used for thicker plates to get a nice sharp edge instead of corner loops. The machine stops at a corner according to the Work Angle, shuts the beam off, and gradually pulses for a commanded distance, at a lower speed, and then it resumes cutting at normal speed. Most machines today have this feature.
I would contact Mazak directly to know more about this feature. If this function does not work for plate, you can easily include this in your program. It would take some effort but the end result would be the same.
Good Luck

Any help will be very gratefully received
RE: More LC1212 questions
Find out when the turbo blower and vacuum pump was last replaced. Also find out if the fanuc resonator has been replaced, ask when was the last time the mirrors have been replaced. I don't know what your budget is but Bystronic has a new laser machine called the Byvention with a small footprint (20'X20') and could cut the following:
Mild Steel - .312"
Stainless Steel - .250"
Aluminum - .160"
The machine can cut a full size sheet (120"X60") in segments of 60"X30" max. Check it out on this website www.bystronic.com
Good Luck,
Hector
RE: More LC1212 questions
many thanks for replying. Afraid our budget isnt a massive one but at the minute we are just pricing things up. Could you breifly explain some of the running costs for me? As I said earlier I have lots of experience in Hy Def plasma but not laser and for years was under the impression laser was expensive to run. It does appear to me though that laser is very much more competetive today.
RE: More LC1212 questions
The running costs of a laser would be:
Optics: Internal and External. Depending on resonator power these could last you anywhere between 4K to 12K hours.
Turbo Blowers: The Fanuc Turbo Blowers usually have a lifespan of about 12K hours.
Vacuum Pump usually gets replaced but it really depends on the machine itself
You would also want to consider your assist gases and your laser gas mix a part of the equation.
The more frequent things to replace of course would be nozzles, lenses, sensor heads, etc.
Good Luck in your search.
RE: More LC1212 questions
The Amada laser is a solid product and the controls are very user friendly. I am not sure about this particular model but most allow are solid.
Amada only uses a standard laser gas so gas costs are extremly low. Lens life should be 3 months if you are running it correctly.
If you are going to cut S/S I'd recommend dedicating a lens just for s/s and alum thus saving wear and tear on reg mat'l and saving the time invlolved in lens cleaning afterwards.
Also, bear in mind, if you are cutting both mat'l types ensure you empty the tray after aluminum as it can ignite once you return to hrs.

Used it for years, loved it.
RE: More LC1212 questions
This you could find used as well or contact Mazak Optonics direct for pricing on this. I am not sure which software they used for this machine but the mazak software is good and is directly supported by Mazak themselves. The benifit to that is all updates and changes can be implemented quickly and any benifits are made direct by Mazak.
Hope this helps.
