The document discusses various computer-controlled machining techniques including: turning, drilling, planning, milling, grinding, electrical discharge machining (EDM), laser cutting, hot wire cutting, and CNC milling. Specific examples of machines that use these techniques are provided from around the world, such as the Omax waterjet cutter, Xact wire EDM, foamlinx hot wire cutter, Epilog laser cutter, Roland modela milling machine, Shopbot CNC milling machine, and Mantis CNC milling machine. Applications from Peru are also highlighted including prototypes fabricated using a MultiCam CNC milling machine.

- 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. EXAMPLES:INTHEWORLD
- 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
- 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
