7.2 Programming of Work Coordinate System (G92)
A coordinate system used for work machining is called the work coordinate system.
The work coordinate system is set by using G92 command.
(G90) G92P ;
This commandestablishes the work coordinate system so that a certain point of the
tool, for example the tool tip, becomes P in the established work coordinate system.
.
Any subsequent absolute commands use the position in this work coordinate system.
(Example 1)
Align the tool tip with the

(When a start point is based on the base point of the tool holder)
As shown above, G92 is also used to align the base point of the tool holder with the
start point and to establish a coordinate system at the beginning of the program.
If an
absolute command is then issued, the base point moves to the position specified in
the work coordinate system, not the machine coordinate system.
