Direct Numerical Control, also known as Distributed Numerical Control, (both DNC) is a common manufacturing term for networking CNCmachine tools. On some CNC machine controllers, 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 Direct to 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 softwares that fulfill the purpose. DNC networking or DNC communication is always required when CAM programs are to run on some CNC Machine control. This article needs to be cleaned up to conform to a higher standard of quality. ... A CNC Turning Center The abbreviation CNC stands for Computer(ized) Numerical(ly) Control(led), and refers specifically to the computer control of machine tools for the purpose of (repeatedly) manufacturing complex parts in metal as well as other materials, using a program written in a notation conforming to the... A machine tool is a powered mechanical device, typically used to fabricate metal components of machines by the selective removal of metal. ... In engineering and mathematics, control theory deals with the behavior of dynamical systems over time. ... Integrating computer-aided manufacturing (CAM) with computer-aided design systems produces quicker and more efficient manufacturing processes. ...
Distributed NumericalControl where by NC programs are sent (distributed) to the memory of a CNC machine.
The directcontrol of a number of separate CNC machine tools by a large central host computer; part programs are downloaded directly into the memory of a CNC machine tool.
DirectNumericalControl A process of controlling a number of CNC equipped machines from a mainframe computer handling the scheduling or work and downloading complete programs into the machines memory.
The hard-wired NC controller unit means that the control features cannot be easily altered to incorporate improvements to the unit.
Directnumericalcontrol is defined as a manufacturing system in which a number of machines are controlled by a computer through direct connection in real time.
Adaptive control or AC determines the proper speeds and/or feeds during machining as a function of variations in such factors as work-material hardness, width or depth of cut, air gaps in part geometry and so on.
