Engraving

engraverengravedengravings
Laser engraving, which is a subset of laser marking, is the practice of using lasers to engrave an object.
Traditional engraving, by burin or with the use of machines, continues to be practised by goldsmiths, glass engravers, gunsmiths and others, while modern industrial techniques such as photoengraving and laser engraving have many important applications.

Laser bonding

bonding
The term laser marking is also used as a generic term covering a broad spectrum of surfacing techniques including printing, hot-branding and laser bonding.
It differs from the more widely known techniques of laser engraving and laser ablation in that it is an additive process, adding material to the substrate surface instead of removing it.

Galvanometer

In the third method, both the laser and workpiece are stationary and galvo mirrors move the laser beam over the workpiece surface.
Closed-loop mirror galvanometers are also used in similar ways in stereolithography, laser sintering, laser engraving, laser beam welding, laser TVs, laser displays and in imaging applications such as retinal scanning with Optical Coherence Tomography (OCT).

Laser engraving, which is a subset of laser marking, is the practice of using lasers to engrave an object.
Industry: cutting including converting thin materials, welding, material heat treatment, marking parts (engraving and bonding), additive manufacturing processes such as selective laser sintering and selective laser melting, non-contact measurement of parts.

Flexography

Direct laser engraving of flexographic printing cylinders and plates has been an established process since the 1970s.
Such a direct laser engraving process is called digital platemaking.

Anilox

Prior to 1980 anilox rolls were produced by a variety of mechanical processes.
Anilox rolls were originally made using a process of mechanical engraving, utilizing hardened steel tools of various cell counts and cell shapes diamond pecking machine, but modern rolls are laser engraved.

Tool bit

The technique does not involve the use of inks, nor does it involve tool bits which contact the engraving surface and wear out, giving it an advantage over alternative engraving or marking technologies where inks or bit heads have to be replaced regularly.

Pencil

The laser is like a pencil - the beam emitted from it allows the controller to trace patterns onto the surface.

Euclidean vector

vectorvectorsvector addition
There are three main genres of engraving machines: The most common is the X-Y table where, usually, the workpiece (surface) is stationary and the laser optics move around in X and Y directions, directing the laser beam to draw vectors.

Raster graphics

Rasterraster imagebitmap
A second genre is for cylindrical workpieces (or flat workpieces mounted around a cylinder) where the laser effectively traverses a fine helix and on/off laser pulsing produces the desired image on a raster basis.

Optics

opticalopticoptical device
The point where the laser (the terms "laser" and "laser beam" may be used interchangeably) touches the surface should be on the focal plane of the laser's optical system and is usually synonymous with its focal point.

Focus (optics)

The point where the laser (the terms "laser" and "laser beam" may be used interchangeably) touches the surface should be on the focal plane of the laser's optical system and is usually synonymous with its focal point.

Vaporization

It may heat up the surface and subsequently vaporize the material, or perhaps the material may fracture (known as "glassing" or "glassing up") and flake off the surface.

Fracture

Vacuum

If the surface material is vaporized during laser engraving, ventilation through the use of blowers or a vacuum pump are almost always required to remove the noxious fumes and smoke arising from this process, and for removal of debris on the surface to allow the laser to continue engraving.

Collimated beam

The beam is highly focused and collimated - in most non-reflective materials like wood, plastics and enamel surfaces, the conversion of light energy to heat is more than {x%} efficient.
