-
Determine machine settings, and move bars or levers to reproduce designs on rollers or plates.
-
Guide stylus over template, causing cutting tool to duplicate design or letters on workpiece.
-
Measure and compute dimensions of lettering, designs, or patterns to be engraved.
-
Prepare workpieces for etching or engraving by cutting, sanding, cleaning, polishing, or treating them with wax, acid resist, lime, etching powder, or light-sensitive enamel.
-
Start machines and lower cutting tools to beginning points on patterns.
-
Examine engraving for quality of cut, burrs, rough spots, and irregular or incomplete engraving.
-
Remove completed workpieces and place them in trays.
-
Use computer software to design patterns for engraving.
-
Adjust depths and sizes of cuts by adjusting heights of worktables, or by adjusting machine-arm gauges.
-
Position and clamp workpieces, plates, or rollers in holding fixtures.
-
Brush or wipe acid over engraving to darken or highlight inscriptions.
-
Engrave and print patterns, designs, etchings, trademarks, or lettering onto flat or curved surfaces of a wide variety of metal, glass, plastic, or paper items, using hand tools or hand-held power tools.
-
Expose workpieces to acid to develop etch patterns such as designs, lettering, or figures.
-
Neutralize workpieces to remove acid, wax, or enamel, using water, solvents, brushes, or specialized machines.
-
Transfer image to workpiece, using contact printer, pantograph stylus, silkscreen printing device, or stamp pad.
-
Insert cutting tools or bits into machines and secure them with wrenches.
-
Inspect etched work for depth of etching, uniformity, and defects, using calibrated microscopes, gauges, fingers, or magnifying lenses.
-
Set reduction scales to attain specified sizes of reproduction on workpieces, and set pantograph controls for required heights, depths, and widths of cuts.
-
Clean and polish engraved areas.
-
Examine sketches, diagrams, samples, blueprints, or photographs to decide how designs are to be etched, cut, or engraved onto workpieces.
-
Print proofs or examine designs to verify accuracy of engraving, and rework engraving as required.
-
Sandblast exposed areas of glass to cut designs in surfaces, using spray guns.
-
Remove wax or tape from etched glassware by using a stylus or knife, or by immersing ware in hot water.
-
Fill etched characters with opaque paste to improve readability.
-
Prepare etching chemicals according to formulas, diluting acid with water to obtain solutions of specified concentration.
-
Sketch, trace, or scribe layout lines and designs on workpieces, plates, dies, or rollers, using compasses, scribers, gravers, or pencils.
