The following example should illustrate the use of G116 using the example
of a cutting technology. For this, MK_KUNDE = "SCHNEIDEN" (CUT) must be
set. G41 switches on the tangential correction of the tool in this case. After
the transformation has been switched on, the B axis is used to set the
miter−box angle of the cutting tool.

3.2.2.47 G120 Absolute coordinate shift via modal offset
Setting the NC actual position to the programmed value by shifting the
modal offset.
G120 AXES
AXES Axes, whose positions should be set.
With G120, the modal offset is calculated so that the resulting actual
position is equal to the programmed value for the axis address.
The effect is like a coordinate shift with G193, however on the modal offset.
The modal offset can be reset with G121.
N10 G90 In block 30, the internal actual position is set to 30 and the modal offset to
70.
N20 G0 X100
N30 G120 X30 The displayed actual position (actual pos. + modal pos.) is not changed
during this process.
N40 G0 X130 In block 40, 200=130+70 is traveled. The displayed actual position is 200.
