NC
Numerical Control: Numerical control (NC) includes all components of machine tool control: → NCK, → PLC,
HMI, → COM.
NCK
Numerical Control Kernel: Component of NC that executes the → part programs and basically coordinates the
motion operations for the machine tool.
Network
A network is the connection of multiple S7-300 and other end devices, e.g. a programming device via a →
connecting cable. A data exchange takes place over the network between the connected devices.
NRK
Numeric robotic kernel (operating system of → NCK)
NURBS
The motion control and path interpolation that occurs within the control is performed based on NURBS (Non
Uniform Rational B-Splines). As a result, a uniform process is available within the control for all interpolations for
SINUMERIK840D.
OEM
The scope for implementing individual solutions (OEM applications) for the SINUMERIK 840D has been provided
for machine manufacturers, who wish to create their own operator interface or integrate process-oriented
functions in the control.
Operator Interface
The user interface (UI) is the display medium for a CNC in the form of a screen. It features horizontal and vertical
softkeys.
Oriented spindle stop
Stops the workpiece spindle in a specified angular position, e.g. in order to perform additional machining at a
particular location.
Note
A more correct term for SINUMERIK840D controls would be: Computerized Numerical
