The advantages of this approach are that the motors are always moving a known, fixed mass. The gas in question is a carbon dioxide mixture which has been electrically stimulated. There are also several techniques involved with the laser cutting process, which we have touched on briefly above: The main use for a laser machine, explained extensively in this article. This will often automatically stop the laser, before any major damage is caused. We focus solely on state-of-the-art fiber lasers at SPI Lasers. Laser technology has the following advantages: High accuracy We focus solely on state-of-the-art fiber lasers at SPI Lasers. The former involves the creation of thru-holes in a material or dents, like an engraving used in the later process. This is based around a laser beam which is guided, formed, and bundled. There are, however, a number of ways of achieving the X-Y movement: either moving the laser head, moving the workpiece or a combination of both. As futuristic as it sounds, laser cutting is a technology that has been with us for decades. To allow comparison between lasers with different beam diameters we therefore use a factor called the focus f-number, which is the focal length, F, divided by the incoming raw beam diameter, D. The requirements for cutting are as follows: a) high power density and therefore small focused spot size. C02 cutting is most often used on non-metal materials as they have a wavelength of 10.6 micrometres. For a constant focus length lens, increase in the raw beam diameter also reduces both the spot diameter and the depth of focus. By far the most popular use of lasers is for cutting. And laser cutting mainly has four different cutting methods to … We highly advise reading the additional related content: If you’re interested in cutting with a laser after what you’ve read above or you have more questions, then we would be happy to discuss this further. This means that should the laser beam be reflected by the flat sheet it can be transmitted back through the beam delivery optics and into the laser itself, potentially causing significant damage. The gas in question is a carbon dioxide mixture which has been electrically stimulated. This can be for small & fine materials or materials with a much greater level of thickness (e.g. A vast range of materials and thickness sizes can be cut with lasers, making it a handy and adaptable process. This means that they are useful for both metals and non-metals.\n\nHowever, this type of laser machine is made up from expensive pump diodes, which can be costly when needed to be replaced; typically, after 8,000 – 15,000 hours of use. The laser focal spot diameter and the depth of focus is dependent on the raw laser beam diameter on the lens and the focal length of the lens. Unlike fibre lasers, direct diode lasers do not include a brightness-enhancing stage, giving them lower optical losses and higher wall-plug efficiency. There are three major varieties of laser cutting: fusion cutting, flame cutting and remote cutting. This means that they are useful for both metals and non-metals. You can control the beam intensity, length and heat output depending on the material you are working with, and can also user a mirror or special lens to further focus the laser beam.\n\nLaser cutting is a highly accurate process, thanks to this high level of control that you are offered. Able to heat, melt and even vaporise material, lasers are seen as the ideal medium for channelling intense but controllable energy. Because these two requirements are in conflict with each other, a compromise must be made. Click on the infographic below to view the entire image, as only a thumbnail view is shown on this page. This allows copper, brass, and aluminium to be cut without problems. metal sheets). However, for the same reason, direct diode lasers are currently of lower beam quality compared to fibre lasers. Like the crystal method above, fiber lasers belong to the solid state group too.\n\nA beam is created using a ‘seed laser’, which is then amplified using glass fibers and pump diodes. One way they are used is for cutting metal plates. The lens is defined by its focal length, which is the distance from the lens to the focused spot. These dents and holes are essentially cuts, and you’ll often see a cutting laser machine also being used for drilling and engraving too. Drilling is the process of creating dents or thru-holes on or in the surface of a material. Fibre lasers are a member of a family called ‘solid-state lasers’. It also produces a smoother surface finish when cutting thicker materials. Thanks to this, slits with a width as small as 0.1mm can be achieved when using the process. Lasers are used for many purposes. This is the ideal situation optically, but the worse situation mechanically, especially for heavier sheets. The Laser Cutting Process: Analysis and Applications presents a comprehensive understanding of the laser cutting process and its practical applications. As the name may suggest, this is the process of cutting a material using a laser beam. However, this type of laser machine is made up from expensive pump diodes, which can be costly when needed to be replaced; typically, after 8,000 – 15,000 hours of use. However, it is still necessary to be able to prevent damage to the laser while developing the conditions or if something goes wrong with the equipment. The CO2 laser (carbon dioxide laser) is generated in a gas mixture, which mostly consists of carbon dioxide (CO2), helium and nitrogen. Manufacturers have sought to make the manufacturing process easier and more efficient. There are three main types of laser cutting: C02 cutting is achieved using a gas laser. As a general rule the addition of alloying elements reduces the reflectivity of aluminium to the laser, so pure aluminium is harder to process than a more traditional 5000 series alloy. A laser cutting machine is great at cutting a huge variety of materials. The process works by directing the laser beam through a nozzle to the workpiece. The process works by having a focused and precise laser beam run through the material that you are looking to cut, delivering an accurate and smooth finish. Laser cutting is a highly accurate process, thanks to this high level of control that you are offered.

Initially, the beam pierces the material with a hole at the edge, and then the beam is continued along from there. In solid-state lasers, the beam is generated by a solid medium. The narrowest part of the focused beam is generally less than 0.0125 inches (0.32 m… Listed below are just some of the many materials: Whatever the material is that you need to work with and whatever the application, it’s highly likely that laser cutting will more than be up for the task. The most popular approach is known as a 'flying optics' system, where the workpiece remains stationary and mirrors are moved in both X and Y axes. Marking is similar to engraving in that a mark is made but the difference being that the mark is only surface level, while an engraving from laser engraving has much more depth. For this reason simply spraying the sheet surface with a non-reflective coating will not entirely eliminate the problem. Why lasers are used for cutting. "}},{"@type":"Question","name":"What are the three main types of laser cutting? A combination of heat and pressure creates the cutting action. The lens is defined by its focal length, which is the distance from the lens to the focused spot. Once the laser beam has completely penetrated the material at one point, the actual laser cutting process begins. pulsed or continuous wave) to cut a wide range of materials to a high level of accuracy, using a process, which is highly repeatable. The third option is known as a 'hybrid' system, where the laser head is moved in one axis and the material moved in the other axis. The wall-plug efficiency of CO2 lasers is about 10%, which is higher than for most lamp-pumped solid-state lasers (eg ND:YAG lasers), but lower than for many diode-pumped lasers . What Is Laser Cutting? Nowadays most of industrial sheet metal laser cutting is carried out using two types of lasers: CO2 and fibre. A beam is created using a ‘seed laser’, which is then amplified using glass fibers and pump diodes. Melt Cutting. What is the laser cutting process? Article by Ahmad Alshidiq. ","acceptedAnswer":{"@type":"Answer","text":"A laser machine is great at cutting a huge variety of materials. For a constant raw laser beam diameter, decrease in the focal length lens of the focusing lens results in a smaller focal spot diameter and depth of focus. If you enjoyed reading this article, why not register for future articles? For relatively light sheet weights, a fixed optic system can be a viable option, but as the sheet weight increases, accurately positioning the material at high speed can be a problem. To make this a little easier, we have explored the process in greater detail below, looking at how the process works, the different types of laser cutting, its advantages, and where you’ll see it most commonly used. So let’s explore those great qualities and disadvantages more closely. b) long depth of focus to process thicker materials with a reasonable tolerance to focus position variation. Fibre laser sources have the following advantages: Direct diode laser technology is the latest progress in the field of solid-state lasers. The laser cutting process is a non-contact, thermal-based type of process where a laser beam is focused directly on the material, exposing it to the combined heat and pressure, doing the cut. Laser cutting is mainly a thermal process in which a focused laser beam is used to melt material in a localised area. The only other consideration is that the shorter the focal length, the closer the lens is to the workpiece, and therefore more likely to get damaged by spatter from the cutting process. The laser cutting process uses a focused laser beam and assist gas to sever metallic plate with high accuracy and exceptional process reliability. If you would like to receive further updates from us, click here. As the lasing material is stimulated, the beam is reflected internally by means of a partial mirror, until it achieves sufficient energy to escape as a stream of monochromatic coherent light. It can be defined as the distance over which the area of the focused spot does not increase beyond 50%. Initially, the laser is used to pierce the material with a hole at the edge, and then the beam is continued along from there. Engraving is the process of removing a layer of a material to leave an engraving below. Where the laser cutting process needs to start anywhere other than the edge of the material, a piercing process is used, whereby a high power pulsed laser makes a hole in the material, for example taking 5-15 seconds to burn through a 0.5-inch-thick (13 mm) stainless steel sheet. Subscribe to our newsletter to receive the latest news and events from TWI: Coined from the words Light Amplification by Stimulated Emission of Radiation lasers have been a byword for efficiency and quality in materials processing since their advent in the sixties. It all begins from the moment we receive an inquiry and continues through to the shipment of the manufactured parts. The process simply involves the use of a focused laser beam (e.g. The laser beam hits the surface of the material and heats it so strongly that it melts or completely vaporises. The laser cutting process involves focusing a laser beam, usually with a lens (sometimes with a concave mirror), to a small spot which has sufficient power density to produce a laser cut. Fusion cutting is another standard process used in metal cutting, and it can also be used to cut other fusible materials, such as ceramics.. The crystal used also has a much shorter service life than that of a fiber laser.\n\nFiber laser cutting\nThis type of cutting is completed using a fiber laser, the type we manufacture here at SPI Lasers. Fig.1 The laser beam melts the workpiece while the cutting gas blows away the molten material and slag in the incision. A fiber laser is the most useful of the three types.
