13.2 The PLANE function: Tilting the working
plane (option 8)
Introduction
Refer to your machine manual.
The machine manufacturer must enable the functions
for tilting the working plane!
You can only use the
PLANE
function in its entirety on
machines having at least two rotary axes (table axes,
head axes or combined axes). An exception is the
PLANE AXIAL
function.
PLANE AXIAL
can also be used
on a machine which has only one programmed rotary
axis.
The
PLANE
functions provide powerful options to define tilted
working planes in various ways.
The parameter definition of the
PLANE
functions is subdivided 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
Further information: "Specifying the positioning behavior of the
PLANE function", page 606
NOTICE
Danger of collision!
Cycle
8 MIRROR IMAGE
may have different effects in conjunction
with the
Tilt working plane
function. The effect mainly depends
on the programming sequence, the mirrored axes and the tilting
function used. There is a danger of collision during the tilting
operation and subsequent machining.
Check the sequence and positions using a graphic simulation
Carefully test the NC program or program section in the
Program run, single block
operating mode
Examples
1 Cycle
8 MIRROR IMAGE
programmed before the tilting
function without rotary axes:
The tilt of the
PLANE
function used (except
PLANE AXIAL
)
is mirrored
The mirroring is effective after the tilt with
PLANE AXIAL
or
Cycle

2 Cycle
8 MIRROR IMAGE
programmed before the tilting
function with a rotary axis:
The mirrored rotary axis has no effect on the tilt specified
in the
PLANE
function used, because only the movement
of the rotary axis is mirrored
