Seen from above samples, the function of G54~G59 instruction is to move the coordinate origin used by NC to
the point that the coordinates in machine tool coordinate system are preset value; please refer to the operation
section in this manual for the method of presetting.
After returning to the home of machine tool, coordinate systems 1~6 of the workpiece are created. G54 is the
initial mode after electrified. The absolute position of the position screen is the coordinates in current
coordinate system.
In CNC programming of machine tool, unless otherwise specified, the IP of interpolation instruction and other
instructions related to coordinates are the coordinate position in current coordinate system (the coordinate
system used when the instruction is executed). In most cases, the current coordinate system is one of G54~G59,
and machine tool coordinate system are seldom used directly.
2.2.4. Local coordinate system (G52)
Function:
G52 can create a local coordinate system, which is a sub-coordinate system equivalent to G54~G59.
