Such a program is short to punch in manually or to keep around and edit as needed so you can request particular programs from the DNC server. Here is a typical example for a Fanuc machine: In this case, a short program is executed on the CNC Machine to request a file be brought down.

вЂ“ вЂњPull ModeвЂќ: While DNC software is often used in a вЂњpushвЂќ mode, meaning the download is initiated from the DNC Server, it is also possible with the right setup to вЂњpullвЂќ. The answer is to Drip Feed, where the g-codes come to the machine a few at a time when the machine is ready to execute them. Complex g-code programs will often exceed the limits of that memory. вЂ“ Drip Feed: Older CNC machines may have very limited RAM memory. Sophisticated DNC software opens the door to a lot of interesting capabilities:

Typically, either a piece of hardware (in the case of stringing many physical cables) or the right software makes it look to the DNC server PC like it has a whole bunch of serial ports ready to pipeline g-code back to the CNC machine on the other end. To make the connection requires either stringing an RS-232 cable from the server to each machine, or there are many WiFi to RS-232 boxes available in the market. Newer machines have protocols that work entirely over Ethernet (cabled or WiFi), but this is typically an expensive option, so even newer machines may still be using RS-232. This is traditionally done using RS-232 serial connections, like the cable on the right. A menu can beВ called up on the DNC software on that machine that causes a particular part program to be sent to a particular machine.ДNC requires connecting every machine back to the DNC Server thatвЂ™s going to manage that machine. The idea is to control what g-code winds up on a group of CNC machines from a central server. These methods are all fairly manual, but thereвЂ™s a more automated way to transfer g-code to your CNC machines that is called вЂњDNC,вЂќ which stands for вЂњ Distributed Numerical Control.вЂќ Some controllers, like TormachвЂ™s PathPilot, can even interface with Dropbox to make file transfer super easy. Newer machines can connect to your WiFi or cabled Ethernet and access folders on a server. These involve plugging some sort of media into the machine temporarily to transfer the code. ThereвЂ™s the old stand bysвЂ“usb key, floppy disk, PCMCIA, and so forth. How does your shop go about getting g-code part programs on to the various CNC machines on your shop floor?
