Switching on zero offset, G54 to G57
In the NC program, the zero offset is moved from the machine coordinate system to the
workpiece coordinate system by executing one of the four commands G54 to G57.

In the next NC block with a programmed movement, all of the positional parameters and thus
the tool movements refer to the workpiece zero, which is now valid.
Note
The 4 available zero offsets can be used, for example, for multiple machining operations, to
describe 4 workpiece clamping positions simultaneously and execute them in the program.
