8 Cycles
TNC 426/TNC 425/TNC 415 B/TNC 407
MIRROR IMAGE (G28)
Application
This cycle allows you to machine the mirror image
of a contour in the machining plane.
Activation
The mirror image cycle becomes active immediate-
ly upon being defined. The mirrored axis is shown
in the additional status display.
• If one axis is mirrored, the machining direction of
the tool is reversed (except in fixed cycles).
• If two axes are mirrored, the machining direction
remains the same.
The result depends on the location of the datum:
• If the datum is located on the contour to be
mirrored, the part simply “flips over.”
• If the datum is located outside the contour to be
mirrored, the part also “jumps” to another
location.
Input data
Enter the axes that you wish to mirror. The tool axis
cannot be mirrored.
Cancellation
This cycle is cancelled by entering G28 without an
axis.
