Programmable mirroring: MIRROR, AMIRROR

Fu n ctionality
MIRROR and AMIRROR can be used to mirror workpiece shapes on coordinate axes. All traversing motions of axes for
which mirroring is programmed are reversed in their direction.
Programming
MIRROR X0 Y0 Z0
AMIRROR X0 Y0 Z0
MIRROR
The instructions that contain MIRROR or AMIRROR each require a separate block. The axis value has no influence. A
value, however, must be specified.
N o te
Any active tool radius compensation (G41/G42) is reversed automatically when mirroring.
The direction of rotation of the circle G2/G3 is also reversed automatically when mirroring.
See the following illustration for example for mirroring with the tool position shown:
