Glossary
Mode
An operating concept on a SINUMERIK controller. The following modes are defined: → Jog,
→ MDA, → Automatic.
Mode group
Axes and spindles that are technologically related can be combined into one mode group.
Axes/spindles of a mode group can be controlled by one or more → channels. The same
→ mode type is always assigned to the channels of the mode group.
NC
Numerical Control component of the → CNC that executes the → part programs and coordinates
the movements of 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 controller is performed based
on NURBS (Non Uniform Rational B-Splines). This provides a uniform procedure for all internal
interpolations.
OEM
The scope for implementing individual solutions (OEM applications) has been provided for
machine manufacturers, who wish to create their own user interface or integrate technology-
specific functions in the controller.
Offset memory
Data range in the control, in which the tool offset data is stored.
Oriented spindle stop
Stops the workpiece spindle in a specified angular position, e.g. in order to perform additional
machining at a particular location.
