Further information
SCALE X... Y... Z...
You can specify an individual scale factor for each axis, by which the shape is to be reduced
or enlarged. The scale refers to the workpiece coordinate system set with G54 to G57,
G505 to G599.
CAUTION
The SCALE command resets all frame components of the previously activated programmable
frame.
ASCALE X... Y... Z...
The ASCALE command is used to program scale changes to be added to existing frames. In
this case, the last valid scale factor is multiplied by the new one.
The currently set or last programmed coordinate system is used as the reference for the scale
change.
