Mirroring of two axes
The mirroring procedure described above must be performed twice, e.g.:
• the X values are mirrored once.
• the Y values are mirrored once.
This can be performed in any sequence.
The control inverts the signs of the two mirrored coordinates (XY).
The direction of machining and the direction of rotation for circular interpolation remain the
same since they have been inverted twice.

Mirroring of X and Y values
When mirroring the main axes, the workpiece is always mirrored.
Program sections which must be mirrored take the form of self-contained subroutines in the
program. The relevant mirroring function for the contour must then be selected before calling
the subroutine.
