The settable frames are activated in the NC program by means of commands such as G54.
1.3.7 Current workpiece coordinate system
Sometimes it is advisable or necessary to reposition and to rotate, mirror and/or scale the
originally selected workpiece coordinate system within a program.
The programmable frames can be used to reposition (rotate, mirror and/or scale) the current
zero point at a suitable point in the workpiece coordinate system. You will thus obtain the
current workpiece coordinate system.
