3.1.5 Zero offset
3.1.5 Zero offset
The actual position memory, and therefore the actual position display, are referred to the
machine zero point ”M” after traversing to the reference point.
The machining program for the workpiece is referred to the workpiece zero point ”W”.
Machine zero point ”M” and workpiece zero point ”W” are not identical. The dimensions
between the machine zero point ”M” and the workpiece zero point ”W” can vary, depending
upon the type and fixing of the workpiece. The zero offset will allow for this during program
operation.
