Milling with a laser is a three dimensional process that requires two lasers, but drastically cuts costs of machining parts. [2] [7] Lasers can be used to change the surface properties of a workpiece. The appliance of laser beam machining varies depending on the industry. In light manufacturing the machine is used to engrave and to drill other ...
Laser marking on stainless steel A laser engraving machine A laser engraver. A laser engraving machine consists of three main parts: a laser, a controller, and a surface. [2] The laser is a drawing tool: the beam emitted from it allows the controller to trace patterns onto the surface.
Modern machine shop workstation, 2009. A machine shop or engineering workshop is a room, building, or company where machining, a form of subtractive manufacturing, is done. In a machine shop, machinists use machine tools and cutting tools to make parts, usually of metal or plastic (but sometimes of other materials such as glass or wood).
In 1965, the first production laser cutting machine was used to drill holes in diamond dies. This machine was made by the Western Electric Engineering Research Center. [3] In 1967, the British pioneered laser-assisted oxygen jet cutting for metals. [4] In the early 1970s, this technology was put into production to cut titanium for aerospace ...
Laser peening (LP), or laser shock peening (LSP), is a surface engineering process used to impart beneficial residual stresses in materials. The deep, high-magnitude compressive residual stresses induced by laser peening increase the resistance of materials to surface-related failures, such as fatigue, fretting fatigue, and stress corrosion cracking.

This reduces repair costs as a single failed head on a single cylinder can be changed instead of a larger, much more expensive unit fitting all the cylinders. Such a design also allows engine manufacturers to easily produce a 'family' of engines of different layouts and/or cylinder numbers without requiring new cylinder head designs.
Laser beam welding (LBW) is a welding technique used to join pieces of metal or thermoplastics through the use of a laser. The beam provides a concentrated heat source, allowing for narrow, deep welds and high welding rates.
