Engraving has been around for thousands of years as we can see with this 10,000 year old stone carving of a now extinct bovine. But the concept and skill of engraving goes even further back in time to an etched shell around 500,000 years old! This first example of etching was created by our ancient ancestor Homo erectus some 25,000 generations ago.
These days, however, simple stone tools and tedious time by hand have been replaced by computer-aided machines. A complicated array of computer guided lasers, mirrors, and elaborate cooling systems can now burn designs into wood, leather, bone, plastic, glass, metal, and more in a matter of hours.
Cool facts about laser engraving:
- LASER stands for Light Amplification by Stimulated Emission of Radiation.
- The laser beam itself is NOT hot. A laser is nothing more than a beam of concentrated light. It's upon contact with matter (e.g. wood) that changes light energy into heat.
- The focal point of the beam is generally less than a fraction of a millimeter.
- Lasers can etch into diamond, the hardest natural substance.
- Laser engraving is economical, fast, and delivers a repeatable flawless design.
Wood carving, of course, has also been around for thousands of years. The oldest wood working tools date back to 160,000 years ago and were used by our extinct cousins the Neanderthal. Routing, however, is specifically hollowing out a surface area normally using a tool and a table. The first hand held routers were used by the Romans and Egyptians, and the milling machine was invented in the early 1800's.
A modern CNC router consists of a cutting bed, spindle, and a drive and computer system. Just like the laser etcher, the router can cut various types of material like wood, metal, plastic, and stone, and has converted a once time consuming task into an efficient and flawless one.
Cool facts about CNC Routing:
- CNC stands for Computer Numerical Control.
- A CNC router can reduce waste, frequency of errors, and the time the finished product takes to get to market.
- The first commercial NC machines were built in the 1950's, and ran from punched tape (predecessor to modern binary encoded software)
- The spindle (the routing tool) can revolve 8000 to 30,000 revolutions per minute.
