R parameters
Arithmetic parameter that can be set or queried by the programmer of the → part program for any purpose in the
program.
Rapid traverse
The highest traverse rate of an axis. For example, rapid traverse is used when the tool approaches the →
workpiece contour from a resting position or when the tool is retracted from the workpiece contour. The rapid
traverse velocity is set on a machine-specific basis using a machine data element.
Reference point
Machine tool position that the measuring system of the → machine axes references.
Rotary axis
Rotary axes apply a workpiece or tool rotation to a defined angular position.
Rotation
Component of a → frame that defines a rotation of the coordinate system around a particular angle.
Rounding axis
Rounding axes rotate a workpiece or tool to an angular position corresponding to an indexing grid. When a grid
index is reached, the rounding axis is "in position".
Safety Functions
The control is equipped with permanently active montoring functions that detect faults in the → CNC, the →
PLC, and the machine in a timely manner so that damage to the workpiece, tool, or machine is largely
prevented. In the event of a fault, the machining operation is interrupted and the drives stopped. The cause of the
malfunction is logged and output as an alarm. At the same time, the PLC is notified that a CNC alarm has been
triggered.
Scaling
Component of a → frame that implements axis-specific scale modifications.
Selecting
Series of statements to the NC that act in concert to produce a particular → workpiece. Likewise, this term
applies to execution of a particular machining operation on a given → raw part.
