Press the corresponding axis traversing keys to traverse each axis to the reference point.
If an axis is referenced, a symbol ( ) is shown next to the axis identifier and is visible only in the
""REF POINT" window.
Note that axis traversing directions and axis key functions are defined by the machine
manufacturer.

Coordinate systems
As a rule, a coordinate system is formed from three mutually perpendicular coordinate axes. The positive directions of the
coordinate axes are defined using the so-called "3-finger rule" of the right hand. The coordinate system is related to the
workpiece and programming takes place independently of whether the tool or the workpiece is being traversed. When
programming, it is always assumed that the tool traverses relative to the coordinate system of the workpiece, which is
intended to be stationary.
The figure below illustrates how to determine the axis directions.
