Computer Controlled Machining/Cutting

Omax Waterjet

http://www.youtube.com/watch?v=wJK-PZt6lEQ

-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.

FoamLinx Hot Wire

http://www.foamlinx.com/fc2913.html

-Thin metal wire of nichrome or stainless steel heated via electrical resistance to 200ºC aprox.

-Heat vaporises metal

-Expanded Polystyrene (EPS, XPS), Expanded Polypropylene (EPP), Expanded Polyethylene (EPE), and Semi-rigid polyethylene foam (XPE)

-When cutting foam, beware of the hazardous fumes

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
