Protection zone
Three-dimensional zone within the → working area into which the tool tip must not pass.
Quadrant error compensation
Contour errors at quadrant transitions, which arise as a result of changing friction conditions
on the guideways, can be almost entirely eliminated with the quadrant error compensation.
Parameterization of the quadrant error compensation is performed by means of a circuit test.
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 speed of an axis. It is used for example to move the tool from rest position to the
-> workpiece contour or retract the tool from the contour.
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 monitoring 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.
