G54: Select the workpiece coordinate system 1
G55: Select the workpiece coordinate system 2
G56: Select the workpiece coordinate system 3
G57: Select the workpiece coordinate system 4
G58: Select the workpiece coordinate system 5
G59: Select the workpiece coordinate system 6
X_ Y_ Z_: Position of the workpiece coordinate system
The coordinate system used for workpiece machining is called the workpiece coordinate system. This is the
coordinate system that allows the operator to create a program conveniently on the basis of drawings, and to set
any point of the workpiece to be machined as the origin by applying the NC program as it is. After turning on the
power, it is necessary to executing homing for proper application of the coordinate system. When using G54 ~ G59,
it is not necessary to set the coordinate system with G92.

G28 G91 X0 Y0 Z0 (Returning to machine origin where the waypoint is the current position value [G91mode])
G54 G00 G90 X0 Y0 Z0 % Use the 54 workpiece coordinate system and traverse it to the origin rapidly. That is, G54
% Traverse to the origin of the coordinate system rapidly
