Danger of collision!
Cycle 8 MIRRORING can have different effects in conjunction with
the Tilt working plane function. The programming sequence,
the mirrored axes, and the tilting function used are critical in this
regard. There is a risk 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 When Cycle 8 MIRRORING is programmed before the tilting
function without rotary axes:
The tilt of the PLANE function used (except PLANE AXIAL)
is mirrored
Mirroring takes effect after tilting with PLANE AXIAL or
Cycle 19
2 When Cycle 8 MIRRORING is 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
Operating and programming notes:
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 control automatically rescinds the radius
compensation, which also rescinds the M120
function.
Always use PLANE RESET to cancel PLANE functions.
Entering 0 in all PLANE parameters (e.g. all three
spatial angles) exclusively resets the angles, but not
the function.
If you restrict the number of tilting axes with the M138
function, your machine may provide only limited tilting
possibilities. The machine tool builder will decide
whether the control takes the angles of deselected
axes into account or sets them to 0.
The control only supports tilting the working plane
with spindle axis Z.
