3.19 Setting Local Coordinate System G52
When a program is created in a workpiece coordinate system, the subprogram of the workpiece
coordinate system (G54-G59) can be set for easy program. Sub coordinate system is called local
coordinate system.
Machine coordinate system, workpiece coordinate system and local coordinate system
The machine coordinate system is a fixed coordinate system on the machine, it indicates a fixed
position of the machine.
The workpiece coordinate system is a system facilitates workpiece machining, in which the reference
point on the workpiece is taken as the origin point.
Local coordinate system is set on workpiece coordinate system to facilitate the programming of some
machining programs.
Format：G52 IP；…… Set local coordinate system
G52 IP0；……Cancel local coordinate system
IP：Specify the position of the origin point of the local coordinate system in the current workpiece
coordinate system
G52 is G code of the group, which is a non-modal G code.
