Tool Offset Parameters
Chapter 22
22-6
Function
Use this feature to determine how the geometry tool offset takes place.
This parameter determines when the work coordinate system is shifted, and
when the axis position is returned to the programmed position after the
coordinate system shifts.

Figure 22.1 defines the difference between “shift” and “move.”

Shift Move
Coordinate system is
shifted by the amount of the offset,
but the tool remains stationary.
Coordinate values of tool position
changes by the amount of offset.
Coordinate system remains stationary,
but the tool moves by the amount of offset.
Coordinate values of tool position changes
by the amount of offset.

Offset is X--10., Y--.5
Tool position
changes from
X5, Y10, to
X--5, Y5.
If original tool
position is X5., Y10.,
new tool position
is X--5., Y5.
