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)
Parameters
MIRROR
AMIRROR
X Y Z
Example of mirroring milling
Program the contour shown here once as a subprogram and generate the three other
contours with a mirror operation. The workpiece zero is located at the center of the contours.
