Cutting Stained Glass

[bisjoe]

Has anyone tried vector scoring stained glass on the laser instead of using the usual hand cutting wheel? I tried it and it did work for straight lines and gentle curves, but for a more drastic curve it will break randomly. I was using speed 25, power 100, Frequency 5000 at 600 dpi on my 45 watt. Even tapping after scoring didn't work.

To cut tight curves using hand cutter you must not make only one cut at desired cutting line, you have to make multiple circular cuts which are "straighter" (not too tight, pieces shaped as crescent moon). Its like taking small bites. After each cut you break away piece of glass with pliers until you reach your desired cutting line.

Maybe this aproach will work with laser. Make multiple scoring lines in glass, and break away little by little.

Cutting glass with CNC machine, which is better?
Scoring by laser or scoring by tool ?

Scoring with a tool is better than scoring with a laser for glass.

The tool produces a 'V' shaped break line whereas the laser produces a 'U' shaped break line.

There are other differences but I have tried both methods and for me the tool wins hands down.
