11.2 The PLANE Function: Tilting the Working Plane (Software Option 1)
Defining the working plane via a single incremental
spatial angle: PLANE SPATIAL
Application
Use an incremental spatial angle when an already active tilted
working plane is to be tilted by
machining a 45° chamfer on a tilted plane.
Before programming, note the following
The defined angle is always in effect in respect to the
active working plane, regardless 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 working 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 in a non-
tilted working plane, then you simply rotate the non-
tilted plane about the spatial angle defined in the
PLANE function.
Parameter description for the positioning behavior:
See "Specifying the positioning behavior of the
PLANE function", page 365.
Input parameters
Incremental angle?: Spatial 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°
