Newer laser machines operating at higher power (6000 watts, as contrasted with early laser cutting machines' 1500-watt ratings) are approaching plasma machines in their ability to cut through thick materials, but the capital cost of such machines is much higher than that of plasma cutting machines capable of cutting thick materials like steel ...
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 ...
As with other machine tools, CNC (computer numerical control) technology was applied to plasma cutting machines in the late 1980s into the 1990s, giving plasma cutting machines greater flexibility to cut diverse shapes "on demand" based on a set of instructions that were programmed into the machine's numerical control.

The more popular SSLE engraving machines use the Diode Pumped Solid State or DPSS laser process. The laser diode, the primary component which excites a pulsed solid state laser, can easily cost one third of the machine itself and functions for a limited number of hours, [15] although a good quality diode can last thousands of hours.
Digital wet laser minilabs work in the following way: The paper is pulled from a light-tight box called a "magazine" containing a roll of paper and cut into sheets, or sheet paper may be used. [4] After cutting an inkjet printer marks each sheet with up to 80 characters of information spread over 2 lines, before exposure using a scanning and ...
A CNC machine that operates on wood CNC machines typically use some kind of coolant, typically a water-miscible oil, to keep the tool and parts from getting hot. A CNC metal lathe with the door open. In machining, numerical control, also called computer numerical control (CNC), [1] is the automated control of tools by means of a computer. [2]

The Nd:YAG laser is the most common laser used in laser designators and laser rangefinders. During the Iran–Iraq War, Iranian soldiers suffered more than 4000 cases of laser eye injury, caused by a variety of Iraqi sources including tank rangefinders. The 1064 nm wavelength of Nd:YAG is thought to be particularly dangerous, as it is invisible ...
