For sheet metal cutting, the focal length is usually 1.5–3 inches (38–76 mm). [7] [8] Advantages of laser cutting over mechanical cutting include easier work holding and reduced contamination of workpiece (since there is no cutting edge which can become contaminated by the material or contaminate the material). Precision may be better since ...

The same conduction that works against the spot vaporisation of metal is an asset if the objective is to vaporise some other coating away from the metal. Laser engraving metal plates are manufactured with a finely polished metal, coated with an enamel paint made to be "burned off". At levels of 10 to 30 watts, excellent engravings are made as ...
where t is the depth of cut, P is the laser beam power, v is the cutting velocity, and d is the laser beam spot diameter. [5] The depth of the cut is also influenced by the workpiece material. The material's reflectivity, density, specific heat, and melting point temperature all contribute to the lasers ability to cut the workpiece.
It is a power-driven metal cutting machine which assists in managing the needed relative motion between cutting tool and the job that changes the size and shape of the job material. [1] The precise definition of the term machine tool varies among users, as discussed below. While all machine tools are "machines that help people to make things ...
