Description of function
Mirroring is a modal function that is effective as soon as it has been
defined in the NC program.
The control mirrors contours or positions about the active workpiece
datum. If the datum is outside the contour, the control will also
mirror the distance to the datum.
If you mirror only one axis, the machining direction of the tool is
reversed The rotational direction defined in a cycle will remain
unchanged, e.g. if defined within one of the OCM cycles (option167).
Depending on the selected AXIS axis values, the control will mirror
the following working planes:
X: The control mirrors the YZ working plane
Y: The control mirrors the ZX working plane
Z: The control mirrors the XY working plane
Further information: "Designation of the axes on milling machines",
Page 87
You can select up to three axis values.
If mirroring is active, the control displays it on the TRANS tab of the
additional status display.
