Defining the working plane via a single incremental
spatial angle: PLANE RELATIV
Application
Use a relative spatial angle when an already active tilted working
plane is to be tilted by
another rotation . Example: machining a 45°
chamfer on a tilted plane.
Programming notes:
The defined angle is always in effect in respect to
the active working plane, regardless of the tilting
function you used before.
You can program any number of
PLANE RELATIV
functions in a row..
If you want to return the working plane to the
orientation that was active before the
PLANE
RELATIV
function, define the same
PLANE RELATIV
function again but enter the value with the opposite
algebraic sign.
If you use
PLANE RELATIV
without previous tilting,
PLANE RELATIV
will be effective directly in the
workpiece coordinate system. In this case, you can
tilt the original working plane by entering a defined
spatial angle in the
PLANE RELATIV
function.
You can select the desired positioning behavior.

behavior of the PLANE function", page 606
