Numerical control. A CNC turning center Numerical control (NC) is the automation of machine tools that are operated by precisely programmed commands encoded on a storage medium, as opposed to controlled manually via hand wheels or levers, or mechanically automated via cams alone.

Numerical control

Most NC today is computer numerical control (CNC), in which computers play an integral part of the control. 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 post processor, and then loaded into the CNC machines for production. Since any particular component might require the use of a number of different tools – drills, saws, etc., modern machines often combine multiple tools into a single "cell".

History[edit] Description[edit] As the controller hardware evolved, the mills themselves also evolved. MakerBot Industries - Robots That Make Things. Windows. 1 | Get an Arduino board and USB cable In this tutorial, we assume you're using an Arduino Uno, Arduino Duemilanove, Nano, Arduino Mega 2560 , 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.) 2 | Download the Arduino environment Get the latest version from the download page.

Par Daniel Kaplan le 07/05/09 | 8 commentaires | 14,127 lectures | Impression Il n’existe pas aujourd’hui d’”internet des objets”, mais tout au plus une connexion en silos d’objets conçus et régis selon les règles les plus classiques de l’économie industrielle.

Repenser l’internet des objets (3/3) : Industrialiser l’internet

La connectivité des objets et des espaces pourrait même signer la fin de la “parenthèse internet”, celle d’un réseau sans tête, sans finalité et totalement ouvert. Ce serait sans compter sur ceux qui, venant du monde numérique ou du design, s’activent dans le sens contraire : celui de doter le monde physique de certaines des propriétés de plasticité et d’ouverture qui caractérisent le monde numérique. D’internetiser l’industrie, alors que celle-ci rêverait d’industrialiser l’internet….Troisième et dernière partie d’une série de trois articles sur la perspective de “l’internet des objets” – lire la 1re partie et la seconde.

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. In simple words, a CNC is a machine which is controlled by a computer, and used to fabricate 3D objects.

This page will describe the process of building a CNC machine, from the design stage, the required materials and the process itself. Still confused? After seeing the movie, you must have understood how useful that kind of machine is for printing electronic circuit boards or manufacturing robot parts. But as I say – “If there’s a will there’s a way”.
