6.7 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)
Parameters
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 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.
