Special Applications Graphics Machines
Introduction
There are a number of graphics machines that have special purposes. Two
machines that you may encounter in the fleet are the engraver and a
computerized graphics machine.
Engravers
An engraver routes letters and images below the surface of metals and
plastics. Personnel name tags, doorplates, desk plates, and shipboard signage
are all examples of engraved products. Engraving is also done on plaques
and trophies and shadow boxes. Engravers work on the same principle as a
pantograph; that is, a parallelogram with repositionable tracer and drawing
points.
Figure 4-11 shows the similarities between a pantograph and an engraving
rig .
