2.2 Zeros and reference points
2.2.1 Reference points in working space
Zeros and reference points
The neutral position of the machine is obtained from the coordinate axes and the
constructive characteristics of the machine. The zero of the coordinate system is obtained by
defining a suitable reference point on the machine in its neutral position.
The position of the coordinate systems (MCS, BCS, BZS, SZS, WCS) is determined by
means of zeros.
Zero points
Machine zero M
The machine zero M defines the machine coordinate system MCS. All other reference points
refer to the machine zero.
Workpiece zero W
The workpiece zero W defines the workpiece coordinate system in relation to the machine
zero M. The programmed part-program blocks are executed in the workpiece coordinate
system WCS.
