Cycles: Coordinate Transformations | WORKING PLANE (Cycle 19, DIN/ISO: G80, software option 1)

Please note while programming:

The Tilt working plane functions are interfaced to the
control and the machine tool by the machine tool builder.
The machine tool builder also specifies whether the
programmed angles are interpreted as coordinates of
the rotary axes (axis angles) or as angular components
of a tilted plane (spatial angles).
Because nonprogrammed rotary axis values are
interpreted as unchanged, you should always define all
three spatial angles, even if one or more angles are at
zero.
The working plane is always tilted around the active
datum.
If you use Cycle 19 when M120 is active, the TNC
automatically rescinds the radius compensation, which
also rescinds the M120 function.
In the optional machine parameter CfgDisplayCoordSys
(no. 127501) you can specify the coordinate system in
which the status display shows an active datum shift.
