11.5 MIRRORING (Cycle 8,
DIN/ISO: G28)
Effect
The TNC can machine the mirror image of a contour in the working
plane.
The mirroring cycle becomes effective as soon as it is defined in the
program. It is also effective in the Positioning with MDI mode of
operation. The active mirrored axes are shown in the additional status
display.
 If you mirror only one axis, the machining direction is reversed
(except in fixed cycles).
 If you mirror two axes, the machining direction remains the same.
The result of the mirroring depends on the location of the datum:
 If the datum lies on the contour to be mirrored, the element simply
flips over.
 If the datum lies outside the contour to be mirrored, the element
also "jumps" to another location.
Resetting
Program the MIRRORING cycle once again with NO ENT.

If you mirror only one axis, the machining direction is
reversed for the milling cycles (Cycles 2xx). Exception:
Cycle 208, in which the direction defined in the cycle
applies.
