10.2.7 Programmable mirroring (MIRROR, AMIRROR)
Function
MIRROR/AMIRROR can be used to mirror workpiece shapes on coordinate axes. All
traversing movements, which are programmed after the mirror call, e.g., in the subprogram,
are executed in the mirror image.
Programming
MIRROR X0 Y0 Z0 (substituting instruction programmed in a separate NC block)
Or
AMIRROR X0 Y0 Z0 (additive instruction programmed in a separate NC block)
Parameter
MIRROR Absolute mirror image with reference to the currently
valid coordinate system set with G54 to G599
AMIRROR Additive mirror image with reference to the currently
valid set or programmed coordinate system
X Y Z Geometry axis whose direction is to be changed. The value
specified here can be chosen freely, e.g., X0 Y0 Z0.
Example of contour dressing
Program the contour shown here once as a subprogram You can generate the other
contours with a mirroring operation.
