8.3 Axis movements
8.3.1 Linear interpolation at rapid traverse: G0
Functionality
The rapid traverse movement G0 is used for fast positioning of the tool, but not directly for
machining of the workpiece.
It is possible to traverse all axes simultaneously – along a straight path.
For each axis, the maximum speed (rapid traverse) is defined in machine data. If only one
axis traverses, it uses its rapid traverse. If two or three axes are traversed simultaneously,
the path velocity (e.g. the resulting velocity at the tool tip) must be selected such that the
maximum possible path velocity with consideration of all axes involved results.
A programmed feedrate (F word) has no meaning for G0. G2/G3 remains active until can-
celed by another instruction from this G group (G0, G1, G3, ...).
Programming
G0 X... Y.. ; Cartesian coordinates
G0 AP=... RP=... ; Polar coordinates
G0 AP=... RP=... ; Cylinder coordinates (3-dimensional)

Information
Another group of G functions exists for movement to the position (see Subsection 8.3.11
“Exact stop / continuous-path control mode: G60, G64”).
For G60 exact stop, a window with various precision values can be selected with another G
group. For exact stop, an alternative instruction with non-modal effectiveness exists: G9.
You should consider these options for adaptation to your positioning tasks.
