Programming key
Character and character strings that have a defined meaning in the programming language
for → part programs.
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 virtually 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 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.
Rigid tapping
This function allows threads to be tapped without a compensating chuck. By using the
interpolating method of the spindle as a rotary axis and the drilling axis, threads can be cut to
a precise final drilling depth e.g. for blind hole threads (requirement: spindles in axis
operation).
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.
