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

Danger of collision!
Cycle 28 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 28 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 19
2 Cycle 28 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
