ABSTRACT:
A method of identifying workstations that performed work on a workpiece in a work line having a plurality of zones, wherein each zone includes workstations that perform the same type of operation. In accordance with the method, the workpiece is moved to and from workstations by a plurality of autoloaders. After the workpiece is worked on in a particular workstation, an autoloader moves the workpiece to a drop-off station where the workpiece is marked with a mark indicating that the workstation worked on the workpiece. When the workpiece is finished, the workpiece has a plurality of marks disposed in different locations of the workpiece. For each of the marks, the location of the mark in combination with the nature of the mark comprises a code that identifies a particular one of the workstations that worked on the workpiece.
