8 Cycles 8.4 Cycles for Coordinate Transformations MIRROR IMAGE (Cycle 8) TNC 360 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.
