TRAANG oblique angle transformation (option)

7.3.1

Function

Note
The "Inclined axis" option under license is required for the function "Inclined axis (TRAANG)."
The angle transformation or "inclined axis" transformation permits programming in the
Cartesian workpiece coordinate system (WCS) on machines with inclined machine axes, a
typical axis arrangement on grinding machines.
The controller transforms the programmed traversing movements of the Cartesian coordinate
system to the traversing movements of the real machine axes.
Standard case: Inclined infeed axis
