Laser cutting machines use a high-powered laser beam to cut through sheet material The laser is guided by an optical fiber or, in the case of metal cutting, a series of mirrors The laser beam’s wavelength is filtered and amplified, enabling it to cut through many materials Lasers can also be used to engrave and mark surfaces of materials Different laser systems have different power, speed, and efficiency, and can be optimized for various types of work Unlike mechanical cutting methods, which apply pressure to the sheet, lasers emit no heat and do not cause deformation or warping of the material Moreover, the laser beam can be focused in an area smaller than the size of the material’s diameter, which allows for a more precise cut without wasting any material This makes laser cutting an efficient and cost-effective way to manufacture parts in small or large numbers Lasers can be used with a wide variety of materials, from wood to plastic to metals However, the type of laser used depends on the material to be cut and its thickness For example, thicker metals require more power than thin ones, and dense wood requires more power than softwoods In addition to power, other factors that affect the performance of laser cutters include frequency and resolution Frequency is important because it determines how fast the laser pulses, while resolution determines how fine a pattern the laser can make The speed of the laser cutting machine is also important because it determines how quickly or slowly the laser can cut through the material For example, a slow speed will be slower to cut through the material and may not cut all the way through it, while a high speed can burn or melt the edges of the material as it cuts Another way that lasers can cut materials is by thermal stress fracture In https//mucinthanhdatcom/may-dong-lo-xo-xoan-oc-nhuahtml , the laser beam is used to cause a crack in the base material of a part The crack is caused by the difference in thermal expansion between the base material and the deposited layer of the part The crack can then be separated from the base material using a solvent or another method The focus point of a laser is a high-intensity spot at the end of its nozzle The bundled laser light is guided by the lens to a specific point on the workpiece, melting it locally This creates a kerf that is barely wider than the laser beam itself, making it possible to cut detailed shapes without leaving any burrs behind Lasers are especially useful for working with difficult to cut materials like MDF and birch plywood
