MIRROR IMAGE (Cycle 8)
Application
This cycle makes it possible to machine the mirror
image of a contour in the working plane.
L
L
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.
l
If one axis is mirrored, the machining direction
of the tool is reversed. This does not apply with
fixed cycles.
l
If two axes are mirrored, the machining direc-
tion remains the same.
The mirror image depends on the location of the
datum:
l
If the datum is located
on
the mirrored contour,
the part is mirrored directly at the datum.
l
If the datum is located outside the mirrored
contour, the part is mirrored and also jumps to
another location.
