Chapter 3 G Commands

Programming
the absolute coordinates before executing commands;
In G50, when X(U) or Z(W) are not input, the system does not change current coordinates
position as program zero; when X(U) and Z(W) are not input, the system takes the previous setting
position as program zero.
Example:
Before setting coordinate system with G50 After setting coordinate system with G50
Fig.3-54
As Fig.3-54, create the above-mentioned workpiece coordinate system and set (X100 Z150) to
the reference point of program after executing “G50 X100 Z150”.
Note: When No.003 Bit4 is 1(executing tool compensation by coordinates offset), T function is executed,
motion command is not executed and the system creates workpiece coordinate system with G50, the
displayed coordinate value are ones which are defined by G50 adding or subtracting tool compensation
value which is not executed.

3.19 Local Coordinate System
When the programming is executed in a workpiece coordinate system, a sub workpiece
coordinate can be created in the workpiece coordinate system, which is called as a local coordinate
system.
Command format
：
G52 X(U) Z(W)
Command function: when G52 is executed, all workpiece coordinate system can (G54
～
G59)
set a local coordinate system. Origin of each local coordinate system is the
specified position X(U) Z(W) of each workpiece coordinate system.
Corresponding relation of workpiece coordinate systems is shown below:
