Defining The Machining Plane With A Single, Incremental Space Angle: Plane Relative - HEIDENHAIN ITNC 530 - 6-2010 DIN-ISO PROGRAMMING User Manual

Defining the Machining Plane with a Single,
Incremental Space Angle: PLANE RELATIVE
Function
Use an 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.
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 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 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" on page 400.
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 Continue with the positioning properties (see

function" on page 400)
