13. -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

14. 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.

17. -High zinc content wires
-Stable tensile strenght
- Wire diameter >= 20 micrometres
-Electric discharge machining (EDM)
-Material removed by current discharges between 2 electrodes, separated by a
dielectric liquid, and subject to electric voltage
-Materials: Aluminium, Stainless Steel, Copper, Steel, itanium, Bronze, Alloys
-Thick as 300mm
-Power consumption is very high
-For machining electrically conductive materials

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

21. -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

26. 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

'SMALL'
Cropped and Zoomed In
Gaussian Blur and Highlight Sampling (blur added to reduce
noise in original image)
Grasshopper Approximation of Milling Pattern
(automatically generates Shop Bot g-code in real-time)
