keeps till the system is turned off.
Command function : when the position of the machine coordinate system is executed, the tool
traverses to the position at the rapid traverse speed.
Command format: G53 IP ;
Command explanation: G53 is non-modal;
IP_: coordinate values of each axis in the machine coordinate system must bespecified by the
absolute value.
Execution process: As the following figure: the specified axis rapidly moves from A (10, 20) in
the current workpiece coordinate system to point B (-8, -10) in the machine
coordinate system.

Note 1: G53 is non-modal, and is valid in other blocks;
Note 2: G53 specifies the absolute position value in the machine coordinate system. The axis code is ignored
when some axis uses the incremental value code; omitting one of axis means the axis does not move.
When G53 is specified but other axes’ position is not specified, other axes do not move;
Note 3: When G53 is executed, the system cancels the tool nose radius compensation;
Note 4: After the system is turned on, the system performs the manual reference position return or G28
automatic reference position return, and automatically creates the origin position of the machine
coordinate system according to the value set by No. 1240;
Note 5: The machine coordinate system must be set before the system codes G53. So, the system must
execute the manual reference position return or G28 automatic reference position return after it is
turned on; the operation is not operated when the system uses the absolute position encoder;
Note 6: The system executes G53 and G00, G01 in Group 01 in the same block, G00 or G01 only modifies G
modal value in Group 01.
2.15.2 Workpiece Coordinate System Setting G50
A coordinate system used to machining a workpiece is called a workpiece coordinate system. A
set workpiece can set again the position of workpiece coordinate system by changing its origin
position. G50 is used to setting a workpiece coordinate system in A set of G code system and G92 is
used to setting a workpiece coordinate system in B set of G code system.
Command function: absolute coordinates of the current position can be set by setting the
