Specifying the positioning behavior of the PLANE
function
Overview
Independently of which PLANE function you use to define the tilted
machining plane, the following functions are always available for
the positioning behavior:
Automatic positioning
Selection of alternate tilting possibilities (not with
PLANE AXIAL
)
Selection of the type of transformation (not with
PLANE AXIAL
)
NOTICE
Danger of collision!

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
