A marking system for an engraved surface which eliminates hand filling, comprising a dispenser (11, 71) for a flowable marker material which is driven to traverse the engraving, and a controller (5, 6, 7, 35) for the amount and timing of material delivered. The dispenser is carried by a computer controlled X-Y-Z coordinate type machine and a computer program controls movement of the dispenser to traverse the engraving and also a pressure/vacuum controller (35) for material delivery via the dispenser in to the engravure. The dispenser is paired physically with an engraving tool (a) relative to a single head system of the X-Y-Z coordinate machine whereby engraving and filling are implemented within the same equipment with related program. The dispenser is constructed as a floating head to eliminate variations in work surface heights. Engraving and filling of multiple workpieces in one loading is accommodated by use of a locating jig and appropriate program structure. |
