The PLANE function: Tilting the
working plane (software option 8)
Introduction
The machine manufacturer must enable the
functions for tilting the working plane!
You can only use the
PLANE function in its entirety
on machines which have at least two rotary axes
(head and/or table). Exception:
PLANE AXIAL can
also be used if only a single rotary axis is present or
active on your machine.
The
PLANE function is a powerful function for defining tilted
working planes in various manners.
The parameter definition of the
PLANE function is separated into
two parts:
The geometric definition of the plane, which is different for each
of the available
PLANE functions.
The positioning behavior of the
PLANE function, which is
independent of the plane definition and is identical for all
PLANE
functions, see "Specifying the positioning behavior of the
Danger of collision!
If you work with Cycle
28 MIRROR IMAGE in a tilted
system, please note the following
Program the tilting motion first and then define Cycle
28 MIRROR IMAGE:
Mirroring a rotary axis with Cycle
28 only mirrors the
motions of the axis, but not the angles defined in the
PLANE functions. As a result, the positioning of the
axes changes.
Programs created on an iTNC 530 or on earlier TNCs
are not compatible.
The actual-position-capture function is not possible
with an active tilted working plane.
If you use the
PLANE function when M120 is
active, the TNC automatically rescinds the radius
compensation, which also rescinds the
M120
function.
Always use
PLANE RESET to reset PLANE functions.
Entering 0 in all
PLANE parameters does not
completely reset the function.
If you restrict the number of tilting axes with the
M138 function, your machine may provide only
limited tilting possibilities.
The TNC only supports tilting the working plane with
spindle axis Z.
