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.
Several zero offsets are possible in the same program.
1.4 Axes
A distinction is made between the following types of axes when programming:
• Machine axes
• Channel axes
• Geometry axes
• Special axes
• Path axes
• Synchronized axes
• Positioning axes
• Command axes (motion-synchronous actions)
• PLC axes
• Link axes
• Lead link axes
