MIRROR IMAGE (Cycle 8)
Application
This cycle makes it possible to machine the mirror
image of a contour in the machining plane.
Activation
The Mirror Image cycle becomes active as soon as
it is defined:
Mirrored axes are identified in the status display by
the letter S.
• If one axis is mirrored, the machining direction of
the tool is reversed (this holds only for machining
cycles).
• If two axes are mirrored, the machining direction
remains the same.
The mirror image depends on the location of the
datum:
• If the datum is located on the mirrored contour,
the part "flips over."
• If the datum is located outside the mirrored
contour, the part flips over and also moves to
another location.
Input data
Enter the axis that you wish to mirror. The tool axis
cannot be mirrored.
Cancellation
To cancel a mirror image, answer the dialog query
with NO ENT.
