Computer Controlled Machining/Cutting
Omax Waterjet

-No heat damage-Width of cut (1.016 to 1.27 mm)-(0.508 mm)-Green technology/water-losed loop system/abrasive-recycled-Materiales: ubber, foam, plastics, composites, stone, tile, metals, food, paper-(45 cm) thick
After generating the cut path from a PNG file within the OMAX software I was also able to view the cut away in red and tool path with lead-ins in green.

Epilog Laser Cutter
-The beam is reflected internally (mirror) ->to lens (working zone= 0.1mm)
-Directing the output of a high-power laser, by computer, at the material to be cut
-Narrowest part - less than 0.3175 mm
-Precision may be better
-High energy required
