The DNC-Interface (Distributed Numerical Control) allowes a remote control of the control software (WinNC) via a software-protocol. The DNC interface creates a connection between a superordinate computer (production master computer, FMS-computer, DNC-host computer etc.) and the control computer of an NC machine.

After activation of the DNC operation the DNC computer (Master) takes over the control of the NC machine (Client). The entire production control is completely assumed by the DNC computer. The automation devices such as doors, clamping chuck (collet), sleeve, coolant etc. can be controlled by the DNC computer. The actual status of the NC machine is displayed on the DNC computer.
