Path traversing behavior

8.1 Tangential control (TANG, TANGON, TANGOF, TLIFT, TANGDEL)
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>)

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
