Defining the machining plane with a single, 
incremental space angle: PLANE RELATIVE
Function
Use the incremental space angle when an already active tilted 
machining plane is to be tilted by another rotation. Example: 
machining a 45° chamfer on a tilted plane.
Input parameters
U
Incremental angle?:
Space angle about which the
active machining plane is to be rotated additionally 
(see figure at right). Use a soft key to select the axis 
to be rotated about. Input range: -359.9999° to 
+359.9999°
U

function” on page 392)
Abbreviations used
Before programming, note the following
The defined angle is always effective in respect to the 
active working plane, irrespective of the function you have 
used to activate it.
You can program any number of PLANE RELATIVE functions 
in a row.
If you want to return to the machining plane that was 
active before the PLANE RELATIVE function, define the 
PLANE RELATIVE
function again with the same angle but
with the opposite algebraic sign.
If you use the PLANE RELATIVE function on an untilted 
machining plane, then you simply rotate the untilted plane 
about the space angle defined in the PLANE function.
Parameter description for the positioning behavior: See 
“Specifying the positioning behavior of the PLANE 
function,” page 392.
