MIRROR IMAGE (Cycle 8)
The TNC can machine the mirror image of a contour in the working
plane. See figure at upper right.
Effect
The MIRROR IMAGE 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 of the tool is
reversed (except in fixed cycles).
■
If you mirror two axes, the machining direction remains the same.
The result of the mirror image depends on the location of the
datum
■ If the datum lies on the contour to be mirrored, the element
simply flips over — see figure at lower right.
■
If the datum lies outside the contour to be mirrored, the element
also “jumps” to another location — see figure at lower right.
ú
Mirror image axis ?: Enter the axis to be mirrored. You
can mirror all axes, including rotary axes, except for
the spindle axis and its auxiliary axes.
