Laser engraving was the biggest revolution over traditional methods of engraving. The difference in laser engraving is that the machine used for engraving will not be in direct contact with the surface which is to be engraved. Laser is just the tool that will be having direct contact with the surface which is to be etched or engraved.
The use of laser cutting machine has made this process really simple, which was earlier considered a complex process. This new technique has proved it is the best and cheap form considered to older methods which were easier and user friendly but need a lot of care.
The laser beam is so powerful that it needs to be controlled while it's used in industrial use, otherwise, it may cut the surface which was to be engraved actually. These laser engraving machines were introduced in the earlier '90s and all the working of this machine controlled by the computer hardware and the software installed in that.
All these types of automation systems are actually having well-designed hardware and software to control all the operations of the machine. Now the machines are really developed that the picture or design which needs to be engraved can be stored to the computer which controls the operations and the software will simply engrave or mark those designs to the surface.
