Element
4. Reference point
Note
Further details of the points that were considered in the programming of G30 are available in the Chapter "Reference point
approach with intermediate point (G28)". Function G30 is implemented with the cycle 328.spf as with G28.

The coordinate system

The position of a tool is defined uniquely by its coordinates in the coordinate system. These coordinates are defined through
axis positions. If, for instance, the three involved Axes are denoted by X, Y and Z, the coordinates are specified as follows:
X... Y... Z...
The following coordinate systems are used to specify the coordinates:
● Machine coordinate systems (G53)
● Workpiece coordinate system (G92)
● Local coordinate system (G52)

Machine coordinate systems (G53)

Defining the machine coordinate system
The machine zero defines the machine coordinate system MCS. All other reference points refer to the machine zero.
The machine zero is a fixed point on the machine tool which can be referenced by all (derived) measuring systems.
