Mirroring is always about the coordinate axis. In order for the contours to be mirrored to the
exact position where they must be machined, the position of the program start when mirroring
is called must be such that the axes of the coordinate system are located exactly between the
programmed contour and the mirrored contour.
If necessary, the zero of the coordinate system must be offset to the correct position before
mirroring is called in the program.

workpiece
In order to mirror the workpiece at the correct position, the zero must be offset by the value
”a”. This results in the distance of both workpieces from zero being the same. After mirroring,
the zero can be reset to its original position.
