Command explanation: G54
～
G59 are modal.
Note 1: The workpiece is created after the system is turned on and executes the reference position
return. When the system is turned on, it automatically selects G54 as the current workpiece
coordinate system;
Note 2: G54-G59 describing the 6 workpiece coordinate systems can change their positions by the
external workpiece zero offset value or workpiece zero offset value, and their relationship is
as Fig. 2-22;
Fig. 2-23
Note 3: Use the following method to change:
1
）
MDI input changes the workpiece coordinate system zero;
2
）
Use G50 to move the workpiece coordinate system;
Specifying G50 IP_ makes the workpiece coordinate system
（
G54
～
G59
）
to set a new workpiece
coordinate system where the current tool position is consistent with the specified coordinates.
When G50 specifies the relative value, the value adding the previous tool position coordinate
value creates a new coordinate system, but the tool position does not change but the coordinate
system executes the offset as Fig. 2-23:
