The PLANE function: Tilting the working plane (software option 8) 12.2
12.2 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

Danger of collision!
If you work with Cycle 8 MIRROR IMAGE in a tilted
system, please note the following:
If you program mirroring before the tilting of the
working plane, the mirroring also effects the tilting.
Exception: Tilting with Cycle 19 and AXIAL PLANE.
Mirroring a rotary axis with Cycle 8 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.
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. When calculating the axis
angle in the selected axis, the control sets the value
0.
The TNC only supports tilting the working plane with
spindle axis Z.
