Fundamentals
2.12 Coordinate transformations (frames)
Different scale factors
NOTICE
Risk of collision
Please take great care when using different scale factors! Circular interpolations can, for
example, only be scaled using identical factors.
Note
However, different scale factors can be used specifically to program distorted circles.

Programmable mirroring (MIRROR, AMIRROR)

MIRROR/AMIRROR can be used to mirror workpiece shapes on coordinate axes. All traversing
movements programmed after the mirror call (e.g. in the subprogram) are executed with
mirroring.
Syntax
MIRROR X... Y... Z...
AMIRROR X... Y... Z...
Note
Each frame operation is programmed in a separate NC block.
