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.
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 RELATIV
functions in a row.
If you want to return to the working plane that was
active before the
PLANE RELATIV
function, define
the same
PLANE RELATIV
function again but with the
opposite algebraic sign.
If you use the
PLANE RELATIV
function in a non-tilted
working plane, then you simply rotate the non-tilted
plane about the spatial angle defined in the
PLANE
function.
