What does DNC mean in computer?

DNC as used in the manufacturing industry.The term DNC was first used as an acronym for Direct Numerical Control. A system whereby a computer directly controls the actions of a numerically controlled machine. DNC also means Distributed Numerical Control which refers to a DNC system with a server and several machines, each with their own computer overseeing the actions at that machine.When we think DNC, our thoughts go to the current DNC systems available today. Today's DNC systems work as follows. Usually there is a DNC server running DNC software and some sort of RS232 controller card, Ethernet connected serial hub appliances or Wireless CNC devices. These devices show up as comm-ports on the DNC server, the DNC software uses these comm-ports to communicate to the CNC machine since most of the CNC machines use standard RS232 communications. DNC systems are also useful on machines equipped with optional LAN, these systems can be mixed. When using a DNC server you may send NC-files to and from your machines from any computer on the network, or if you prefer, you may use Remote Request at the machine control with no computer interaction needed by operators. Once you have a DNC system in place, you will have the ability to integrate bar code scanners and other devices to enhance your production. In addition, you will be able to use Machine Tool Monitoring systems.


What is difference between high speed machine and CNC machine?

CNC denotes Computer Numerically Controlled. so, a cnc machine has all its functions ie: speed, axis movement, tooling selection ran by the computer. High speed is just that, so you can get a high speed CNC.


What is the direct control?

Direct numerical control (DNC), also known as distributed numerical control (also DNC), is a common manufacturingterm for networking numerical-controlmachine-tool. On some CNC machine control-theory, the available memory is too small to contain the machining program (for example machining complex surfaces), so in this case the program is stored in a separate computer and sent directlyto the machine, one block at a time. If the computer is connected to a number of machines it can distribute programs to different machines as required. Usually, the manufacturer of the control provides suitable DNC software. However, if this provision is not possible, some software companies provide DNC applications that fulfill the purpose. DNC networking or DNC communication is always required when computer-aided-manufacturingprograms are to run on some CNC machine control.

I would go for the new one. It will still have a warranty. It should make any difference worth it.

What is the difference between DNC and RNC?

A lot more of "we" and DNC rather "me" at the RNC, also people look like there having a great time there. On other note RNC slammed the president over and over. And did not say one thing about a plan to fix our country. DNC ; they have been stating facts (in my opinion) and tell us what there doing to keep us on the right track to a better place for us and our children. That's the difference I have seen . God bless America! Go OBAMA!

What is the diference between nc and cnc?

nc is numerical control cnc is computer numerical control nc came before cnc in the form of tape reading machines in which the tape was punched with holes to indicate positions. cnc began when microprocessors were used to interpret the data and it was stored digitally rather than in tapes.
