9.7 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
8 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°
8 Continue with the positioning properties (see
“Specifying the Positioning Behavior of the PLANE
Function” on page 531).
Abbreviations used
Before programming, note the following:
The defined angle always applies to the active machining
plane, no matter which function you used to activate it.
You can program any number of PLANE RELATIV functions
in a row.
If you want to return to the machining plane that was
active before the PLANE RELATIV function, redefine the
PLANE RELATIV
function with the same angle but with the
opposite algebraic sign.
If you use the PLANE RELATIV 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 531.
