The program compiled by the optical fiber laser cutting machine no longer needs manual correction, but is a three-dimensional processing program which is completely consistent with the theoretical cutting edge line and can be directly used for cutting products. The laser cutter will focus the laser beam emitted from the laser through the optical system into a high power density laser beam. The laser beam irradiates the surface of the workpiece, so that the workpiece reaches the melting point or boiling point. At the same time, the high-pressure gas coaxial with the beam will blow away the melted or gasified metal. It can ensure that the cutting process is always consistent with the actual cutting edge state, and there is no two-dimensional line that can not be drawn. The whole cutting process does not need manual intervention, from the source to ensure that each product processing is consistent with the digital model, so that the original need to explore many times before the cutting edge can only be completed 3 to 4 times.

　　用光纖激光切割機加工金屬時，線切割精度高，能切割厚板，但其缺點是速度慢。光纖激光切割機利用光纖激光發(fā)生器作為光源的激光切割機。光纖激光器是上新發(fā)展的一種新型光纖激光器輸出高能量密度的激光束，并聚集在工件表面上，使工件上被超細焦點光斑照射的區(qū)域瞬間熔化和氣化，通過數(shù)控機械系統(tǒng)移動光斑照射位置而實現(xiàn)自動切割。有時其他的方法需要穿孔和穿孔來切割，而且切割的尺寸也是非常有限的。激光切割可以沖切材料。切削速度快，加工尺寸范圍比線切割大得多。激光切割目前廣泛應用于金屬加工行業(yè)，激光切割速度快，精度高。中薄板、鋁板、不銹鋼等金屬板材的切割具有優(yōu)勢，這就是光纖激光切割機不可替代的原因，相信隨著人們對激光切割產(chǎn)品需求的不斷增加，光纖激光切割的機會也越來越多。

　　When metal is machined by optical fiber laser cutting machine, WEDM has high precision and can cut thick plates, but its disadvantage is slow speed. Fiber laser cutting machine uses fiber laser generator as light source. Fiber laser is a new type of fiber laser developed in the world. It produces high energy density laser beams and gathers on the surface of the workpiece, which instantly melts and gasifies the area illuminated by the ultra-fine focus spot, and realizes automatic cutting by moving the spot illumination position through the numerical control mechanical system. Sometimes other methods need perforation and perforation to cut, and the size of cutting is very limited. Laser cutting can cut materials. The cutting speed is fast and the processing size range is much larger than that of wire cutting. Laser cutting is widely used in metal processing industry. Laser cutting is fast and accurate. The cutting of sheet metal, such as medium and thin plate, aluminium plate and stainless steel has absolute advantages, which is the reason why the optical fiber laser cutting machine can not be replaced. I believe that with the increasing demand for laser cutting products, the opportunities of optical fiber laser cutting are also increasing.

　　There are many differences between optical fiber laser cutting machine and other cutting methods. Fiber laser cutting machine uses fiber laser generator as light source. Fiber laser is a new type of fiber laser developed in the world. It produces high energy density laser beams and gathers on the surface of the workpiece, which instantly melts and gasifies the area illuminated by the ultra-fine focus spot, and realizes automatic cutting by moving the spot illumination position through the numerical control mechanical system. For the cutting of some metal parts, the punching and shearing process can be adopted, which has high efficiency and high speed. And the cost is also very low, but it requires specific dies and tools to cut, can only be punched on the thinnest sheet, and the laser cutting of optical fiber laser cutting machine is more flexible than the cutting method, any shape of the workpiece can be cut at any time, without the need for points on the die.

　　沖切工藝難以或不可能實現(xiàn)，因此并沒有得到廣泛的應用?；鹧媲懈钜彩墙饘兕I域中常用的切割工藝之一。切割的厚度范圍也很大，但與激光切割相比，切割表面的質(zhì)量和精度相對較差，但厚板和加工的范圍要大于激光切割的范圍。因此，光纖激光切割機一般是用來切割較精細的。

　　Punching process is difficult or impossible to achieve, so it has not been widely used. Flame cutting is also one of the common cutting processes in metal field. The thickness range of cutting is also large, but compared with laser cutting, the quality and precision of cutting surface are relatively poor, but the thickness and processing range of thick plate are larger than laser cutting range. Therefore, optical fiber laser cutting machine is generally used to cut more fine.
