Numerical control - Wikipedia, the free encyclopedia
Numerical control ( NC ) refers to the automation of machine tools that are operated by abstractly programmed commands encoded on a storage medium, as opposed to controlled manually via handwheels or levers, or mechanically automated via cams alone. The first NC machines were built in the 1940s and 1950s, based on existing tools that were modified with motors that moved the controls to follow points fed into the system on punched tape . These early servomechanisms were rapidly augmented with analog and digital computers, creating the modern computer numerical control ( CNC ) machine tools that have revolutionized the machining processes. In modern CNC systems, end-to-end component design is highly automated using computer-aided design (CAD) and computer-aided manufacturing (CAM) programs. The programs produce a computer file that is interpreted to extract the commands needed to operate a particular machine via a postprocessor , and then loaded into the CNC machines for production.
Grande Yellow Cat Fixup It's a toy tiger. Printed on a makerbot replicator. I started with the grande yellow cat source, but ReplicatorG couldn't render it to gcode and print, so I used rhino to clean up the model and remove the grass base that's on the model but not in the original picture.
MakerBot Industries - Robots That Make Things.
In this tutorial, we assume you're using an Arduino Uno , Arduino Duemilanove , Nano , or Diecimila . If you have another board, read the corresponding page in this getting started guide. You also need a standard USB cable (A plug to B plug): the kind you would connect to a USB printer, for example. (For the Arduino Nano, you'll need an A to Mini-B cable instead.)

MakerBot CNC | One Sweet Cupcake
While recently exploring the world of CNC — MakerBot popped up during a search at gizmodo.com . After checking this out and getting excited that the DIY unit was just $750 — I had to have one. The MakerBot video shows the Cupcake in action.Repenser l’internet des objets (3/3) : Industrialiser l’internet

I'm afraid I don't have the space (or the expertise for that matter) to go into the fundamentals of CNC here but there is one websites in particular I found quite useful in my research.

Home-Made DIY CNC Machine using Step Motors, Dremel, and EMC2
The abbreviation CNC stands for computer numerical control, and refers specifically to a computer “controller” that reads G-code instructions and drives a machine tool, a powered mechanical device typically used to fabricate components by the selective removal of material. After seeing the movie, you must have understood how useful that kind of machine is for printing electronic circuit boards or manufacturing robot parts. This kind of machine helped tremendously cut the prototype manufacturing costs, and thus very useful for me. The only problem is – such a machine costs thousands of dollars.
