the workpiece coordinate system G54~G59. The origin of the local
coordinate system can set in the position specified by IP_ in the workpiece
coordinate system. The corresponding relationship is as Fig. 2-26.

Command format: G52 IP__; set the local coordinate system
……
G52 IP0; cancel the local coordinate system
Command explanation: G52 is non-modal;
IP_: when IP_ is absolute code, the system specifies the absolute coordinate value of origin of
local coordinate system in the workpiece coordinate system; when IP_ is the incremental
code, the execution result is the same that of the absolute code;
Once the local coordinate system is created, its coordinates are used to the axis motion code.
Using G52 to code the zero of the new local coordinate system in the workpiece coordinate
system can change the position of the local coordinate system. making the zero of the local
coordinate system coincide with the one of the workpiece coordinate system can cancel the local
coordinate system and returns to the workpiece coordinate system, i.e. code G52 X0 Z0 or G52
U0 W0.
Note 1: The local coordinate system setting does not change the workpiece coordinate system and the
machine coordinate system;
Note 2: Executing G52 can temporarily cancel the offset in the tool nose radius compensation;
Note 3: In local coordinate system, when G50 sets the workpiece coordinate system and the system has
not specified the coordinate values to all axes in the local coordinate system, the axis which is
not specified in G50 in the local coordinate system still keeps, the local coordinate system
corresponding to G50 axis is cancelled; For example:
G52 X50 Z50;
……
G50 X100; at the moment, Z coordinate value is not change, the local coordinate system
corresponding to X is cancelled
Note 4: When the system selects the workpiece coordinate system code

to change the
workpiece coordinate system in the local coordinate system, the local coordinate system also
moves to the new workpiece coordinate system.
Note 5: Whether the local coordinate system in reset is cancelled is determined by No.1202 Bit 3(RLC) ,
the local coordinate system is cancelled in reset when the parameter is set to 1.
Note 6: Whether the local coordinate system in manual reference position return is cancelled is
determined by No.1201Bit 2 (ZCL), the local coordinate system is cancelled in manual reference
position return when the parameter is set to 1. When G28 and G30 execute the reference point
return, the system does not cancel the local coordinate system.
