Brief description

Function
The "tangential control" function belongs to the category of NC functions with coupled axes.
The function has the following characteristics:
● There are two leading axes (guide axes) which are moved using standard traversing
● The leading axes are defined as geometry axes and the following axis as a rotary axis.
● The coupled axes are axes in the same NC channel.
● The position of the following axis can be the input value for a transformation.
● Tangential control is only active in AUTOMATIC or MDA modes.
Application examples
● Positioning and tangential tracking of a rotatable tool during nibbling.
● Tracking of the workpiece alignment for a belt saw.
● Positioning and tangential tracking of a dressing tool on a grinding wheel.
● Tangential tracking a small cutting wheel when machining glass or paper.
● Tangential feed of a wire for 5-axis welding.
Defining, activating, deactivating the axis coupling
A program instruction defines the tangential axis coupling. Additional activation and
deactivation instructions exist in the program.
Deleting an axis coupling
The definition of a tangential axis coupling may be deleted by means of a program
instruction. An axis coupling with this following axis can then be defined again.

instructions and therefore traverse a path. A following axis also exists and its movement
is dependent on this path contour (on the direction of the tangent in the current point on
the path).
