Application
Tangential control can e.g. be used in the applications:
● Tangential positioning of a rotatable tool during nibbling
● Tracking the workpiece alignment for a bandsaw (see the following diagram).
● Positioning of a dressing tool on a grinding wheel
● Positioning of a cutting wheel for glass or paper working
● Tangential feed of a wire for 5-axis welding.

Syntax
Defining tangential tracking:
TANG(<Faxis>,<Laxis1>,<Laxis2>,<coupling factor>,<KS>,<Opt>)
Activating tangential control:
TANGON(<Faxis>,<angle>,<Dist>,<angular tolerance>)
Deactivating tangential control:
TANGOF (<Faxis>)
Activating the "Insert intermediate block at contour corners" function:
TLIFT(<Faxis>)
The
TLIFT operation is specified after the axis assignment with TANG(...).
Deactivating the "Inserting intermediate block at contour corners" function:
Repeat the
TANG(...) operation without a following TLIFT(<Faxis>).
Deleting definition of tangential tracking:
TANGDEL(<Faxis>)
An existing user-defined tangential tracking must be deleted if a new tangential tracking with
the same following axis is defined in the preparation call
TANG. Deletion is only possible if the
coupling with
TANGOF(<Faxis>) is deactivated.
