8 Cycles 8.4 Cycles for Coordinate Transformations MIRROR IMAGE G28 TNC 360 Application This cycle makes it possible to machine the mirror image of a contour in the working plane. Activation The MIRROR IMAGE cycle becomes active as soon as it is defined. Mirrored axes are identified in the status display. • If one axis is mirrored, the machining direction of the tool is reversed. This does not apply to fixed cycles, however. • 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 "turns over" at that point. • If the datum is located outside the mirrored contour, the part turns over and also "jumps" to another location. Input data Enter the axis that you wish to mirror. The tool axis cannot be mirrored. Cancellation To cancel the mirror image, program G28 without defining an axis.
