Laser cutting metal gears

Hi All
In about a months time I will receive a 1kW fiber laser for cutting metal. I hope to be able to cut functional gears on it. I know they will not be suitable for heavy duty use as the cut faces aren't perfectly straight on a laser. However I hope they will be good enough for light duty in Rolling Ball Sculptures.
Has anyone in the group ever cut metal gears on a laser or have had some cut?
Cheers,
Michael

Michael;
No metal gears for me, however they cut and work great on wood or plastic. I don't suspect you'll have any issues as long as the curf from the cut line has been taken into consideration. Good Luck and have fun.
Cheers
Bob

How thick are the gears going to be? Something you might want to consider is two make two thinner gears with dowel pin holes. Then sandwich them together and secure with dowel pins.

The gears will probably be in the 3-6mm range.
I've cut loads of wood and plastic gears on my CO2 lasers and they work fine in my marble machine kits where there is little load.

Just cut these mod2 gears on the fiber laser. 3mm carbon steel. Good enough for kinetic art pieces.

Hi :
Great job on those. I've never used a 1kw fiber.. how long did it take to cut?
The results look good. 3mm thick is pretty impressive really by laser.

Didn't time it - probably less than a minute. 1kW is small stuff by todays standards. 6kW seems the norm with the big guys.
Here is one being cut in 1mm steel:

Wow, the gears cut really fast and appear to have fairly smooth teeth. Thanks for posting the video.

I can just about manage mod0.5 in thin materials. Once the width of the tooth goes below the thickness of the sheet, then burning starts to become an issue.

Really nice job. Can you give us the name of the fiber laser or better yet a link?
