Glossary
Tool
Active part on the machine tool that implements machining (e.g. turning tool, milling tool, drill,
LASER beam, etc.).
Tool nose radius compensation
Contour programming assumes that the tool is pointed. Because this is not actually the case
in practice, the curvature radius of the tool used must be communicated to the controller
which then takes it into account. The curvature center is maintained equidistantly around the
contour, offset by the curvature radius.
Tool offset
Consideration of the tool dimensions in calculating the path.
Tool radius compensation
To directly program a desired → workpiece contour, the control must traverse an equistant
path to the programmed contour taking into account the radius of the tool that is being used

G41
Transformation
Additive or absolute zero offset of an axis.
Travel range
The maximum permissible travel range for linear axes is ± 9 decades. The absolute value
depends on the selected input and position control resolution and the unit of measurement
(inch or metric).
User interface
The user interface (UI) is the display medium for a CNC in the form of a screen. It features
horizontal and vertical softkeys.
User memory
All programs and data, such as part programs, subprograms, comments, tool offsets, and
zero offsets/frames, as well as channel and program user data, can be stored in the shared
CNC user memory.
