Laser cutting parameters

The cutting speed depends on the heat energy output from the laser, and the material Thickness and properties.

It should be set up for the optimum speed already. If you have too much heat ,the system is too slow, or the material is thinner then designed; heat damage will result. On the other hand, if the system is underpowered, too fast, or the material is too thick; incomplete cutting will occur.

Speed adjustment depends on your control system. If it is a computer, you should have different settings for each material, titanium, or Nickel. You should also have different settings for the thickness of the material.

Most laser cutters for sheet material use a high power Co2 laser that is pused accoding to the material concerned. The narrower the beam the betther the over all cut. Then match the materials feed speed to the lasers power out put.

Hi,

which type of laser: wavelength, power, pulsed: shape of pulse and duration and repetition frequency?

which type of focusing lens: diameter and focal length?

any supporting gas flow: type and nozzle and pressure and flow rate?

which thickness range of materials?

Get and poste a table of thermal conductivity of materials you have to cut together with today achieved cutting speed and thickness in order to decide whether thermal conductivity is the limiting factor.

can I speed up laser beam cutting?

Why Can't you Slow down for a change.

Haste is waste!

Narrow low-power Beam will also give you minimum Kerf loss

If possible, I would use a water cutter instead. They can typically run through tough materials like that much faster. I'm not sure what abrasive would be right for those materials, maybe garnet.

Out of curiosity, why only go for rough dimensions with a laser cutter? They are extremely accurate. Or is that because of the heat effected material? Water cutters can keep the part cool and eliminate that.

If you can't use a water cutter, there are some simple ways to speed laser cutters that you may or may not have already done. Mainly, buy a new one with higher power. Cheaply, spend more time on the program - make sure your drawing never has lines that lay over each other, as the machine will cut there twice, check that the tool path is logical and not skipping around stupidly, as can happen with complex parts. Have multiple parts share edges as much as possible so single cuts help out more than one part. Also, talk to the cutter manufacturer and make sure you are using the optimum gap and depth of cut settings for the material/thickness.

If water is not an option, and you want much faster, and have lots of cash laying around, try a plasma cutting machine. Navy contractors use those to cut several inch thick steel plates to make ship parts (FAST).

you need a bigger laser...my laser goes to 11!

Play with the settings...boost the power...tweek the speed...untill your cycle time and cut quality are using the machine the best possible. Test with some scrap...make a simple program to do some simple geometry if material is limited...thats what I would do :)
