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.
