HEIDENHAIN TNC 430 - MIRROR IMAGE (Cycle 8)

HEIDENHAIN TNC 426, TNC 430 325
8.8 Coordinate Transformation Cycles
MIRROR IMAGE (Cycle 8)
The TNC can machine the mirror image of a contour in the working
plane.
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.
n If you mirror only one axis, the machining direction of the tool is
reversed (except in fixed cycles).
n If you mirror two axes, the machining direction remains the same.
The result of the mirror image depends on the location of the datum:
n If the datum lies on the contour to be mirrored, the element simply
flips over.
n If the datum lies outside the contour to be mirrored, the element
also “jumps” to another location.

If you mirror only one axis, the machining direction is
reversed for the new machining cycles (cycles 2xx). The
machining direction remains the same for older machining
cycles, such as Cycle 4 POCKET MILLING.
