ABSTRACT:
A component part number marking or engraving machine has a microprocessor controlled marking or engraving tool in which a range of part numbers, and the corresponding instructions for operating the tool are stored in memory. Upon calling up the appropriate instruction set a selected part number is automatically marked or engraved on a component. The present invention provides a fixture for receiving the component and has a plurality of sensors responsive to the physical dimensions of a range of components and disposed so as to uniquely identify each type of component in the range. Each valid combination of sensors signals is indexed against the appropriate part number and is used to retrieve the corresponding engraver operating instructions from memory.
