Raise cut machine to machine efficiency with fiber coupling laser

Fiber coupling laser opened new perspective for systematic manufacturer and user. Energy-saving and increase quantum of output, the cut technology that helps this spirit live machines a respect to improve productivity apparently in thin plate especially, premise is answer with this technology mutual and applicable. In the past in 10 years, in company of treatment of the reckon by the piece inside limits of Laser Cutting alive bound and the application in producing enterprise batch to machine, like studying an activity, the international related to this respect experienced considerable continuity development. Of a variety of innovation on the material as automation of technology of laser source, machine, process and need cut appear, subsequently and those who come is worldwide inside be in change all sorts of requirements on the economy in the center and zoology. In the fair that holds recently, like Hannuowei Euroblech exposition and international major conference were like the Icaleo meeting that American Anaheim holds to go up 2010, the technical standard that all can make a person see Laser Cutting respect is current impressively develops a tendency with what did not come. In 5 years of in the past, the occurrence of fiber laser and vitreous laser, make traditional CO2Laser Cutting market becomes flabbier and flabbier decided. According to the perspective different, systematic manufacturer, user and research organization are differ to the response that this makes, express to reject to face the opportunity that will open from the menace that faces pair of traditional markets and be without reservation to express to welcome. Should when the cloud opens mist to come loose, the likelihood still needs a certain number of year. During this, the function of new-style laser is impossible cancel totally. On the other hand, technology of CO2 carbon laser withholds the standard that come down to still also be worth to take seriously. Though such, the expensive system efficiency of technology of laser of 1 μ M and Gao Ke use fiber coupling quality, include to adjust cost of face, operation decreases with what uphold charge, still gained the attention of the market. The warm-up of resonator does not have time loss, the guiding of beam of light need not be supplied again rinse gas, also need not redo is fixed (or nonsked) compensatory calibration, these traditions that share hardship to the course are strong argument for the user of laser technology. Though is such, the limitation of the cut quality respect that the system of laser of 1 μ M of fiber coupling can gain when cut of old stuff ply still impassable. Nevertheless, this kind of technology gets certain client market approbate, and study through ambitious effort, also push again and again to bigger plate thickness. Graph 1 high speed cut 1.

The automobile body board with large 2mm is in early last centuries 90 time, before equipment of cut of type of flat of laser of the first glass appeared on the market 2008, trumpf company rolled out the equipment of flat type Laser Cutting of fiber coupling to the market, its foundation is optical pump Nd:YAG laser, shoot bundle of quality to still be 12 Mm*mrad. The precursor of technology of new-style Laser Cutting is the Cy-Laser of Sahajanand company of India and Italian Finsomac group. Both all installed equipment of the first batch of Laser Cutting 2005. Although also do not count dinkum tubal treatment and 3D equipment,come in, inside the market survey range that in Fulaoenhuofeier ILT institute not long ago makes, the whole world has investigated the device of cut of flat of laser of fiber-optic coupling Multi-kW- that gave 24 family expenses to be machined at armor plate, if these companies' corresponding main product assemble pursues 2. Graph the fiber coupling laser of 24 2 production firms that form alphabetically makes the same score provider of machine of bed cut equipment to differ 5 the laser source of the company is compositive together, among them IPG offerred them in the center the fiber laser of 2/3 above. The machine manufacturer of 1/4 belongs to the person that the world market with famous equipment of cut of Multi-kW- laser flat precedes, because make,the manufacturer to this day that has 1/3 above basically is use plasma and blaze cut and strong cut and water the machine of fluidics and gave a name. They seize this opportunity, enlarged oneself product range. Among them a few companies still are in in a machine mix head of one or more Laser Cutting afore-mentioned traditional cut technology mix rise use. Laser source is mixed in the cut rate that can achieve the latent capacity that place of cut quality field has, also using appropriate laser to shoot bundle of telescope and cut gas nozzle, process at the same time only sensor and adjust function and tigidity and efficient armor plate install loop, enough machine trends buy of remove stage makeup and costume, try to fulfil ability in practice significant. Still must satisfy relevant safe provision in addition. Mix in outline of dimension of limits of material, ply, spare parts, cut finally what action decides since necessary crop respect is the cut equipment that serves as a project mix currently prospective utility, it is the solution that it is deciding which kinds of system to offer most economy is economical. The premise that understands basically to Laser Cutting is the detailed observation to process. High speed is photographed resemble offerring very high resolution on time and space, can observe the dynamic condition of Laser Cutting process. The laser that ILT institute uses wavelengh of 10 μ M and wavelengh of 1 μ M with this kind of means is able to discover and making clear is opposite Fulaoenhuofeier the fundamental difference when stainless steel cut. The photograph of other process parameter that should use besides wavelengh falls with the circumstance, the frit current of the dynamic wave motion when use fiber laser and flowing below CO2Laser Cutting circumstance and even openly cut phenomenon are having apparent difference (graph 3) . Laser of Nextpage graph 3 CO2 (left) with fiber Laser Cutting4mm high speed photographs the cut front of thick stainless steel to be in like the picture the precursory sex that goes up to parameter dependency understanding, become nowadays of successful in global competition design to machine the key of process. If need pair of optimized system designs and proper process parameter to make prophecy and the word that won't waste resource because of a large number of time-consuming and arduous tests, that emulates the tool that calculate even if can offer an alternative. Can describe stationary process monitoring and withstand has a test on broad battle line relative the model of Laser Cutting theory that has adequate level is little little. Nevertheless, whether must mix to the cut rate that can achieve the reason of cut quality goes thinking deep, whether can perhaps calculate piece to regarding a process as parameter (like wavelengh, shoot bundle power and quality, get together bundle of coefficient and focal position) the speed limit that action decides since functional quality and process character, there is very big difference again among this (graph 4) . Graph the fixed condition of front of CO2Laser Cutting of 4 emulation computation ILT institute uses Fulaoenhuofeier emulation program Calcut is opposite multiple reflex causes when the laser cut that adopts wavelengh of 1 μ M those who raise rate is active. Current, the dynamic function of cut process also gets fundamental theory is analysed increasingly. The improvement of computer hardware and digital method, be opposite laser / gas / when the interact in data system has the consideration related to time and do in opposite Cheng result forecasted a respect to offer significant progress. Be in on international this domain efforts also is in grow day and day, also will be opposite ceaselessly henceforth of Laser Cutting process uncover further blow hair drier closely. Laser Cutting system includes source of a laser, shoot bundle guide and shoot bundle shape telescope, one is used at beam of light and material pilot machine and unit of a control. Laser source offers laser power and laser quality. The wavelengh of laser of 1 μ M is shorter, effectively cut includes red copper and brass inside nonferrous metal. Cut is metalloid also have laser plan. Especially composite material, increase like fiber model plastic, the port nowadays is more and more principal, carrying a territory for example. Because be in metalloid medium absorption is very tall, this opened the good good luck that enters new-style market for CO2 laser. Of kilowatt class exceed short arteries and veins to because have,be shot nonlinearly to laser bundle - material interaction and can undertake protective data but very significant however cut, also will have more and more important sense in the future. Use the freedom that shoots bundle of quality laser high to obtain to spend, return at present far did not dig almost to use up. The improvement that this kind of laser offers latent capacity was head and shoulders above current parameter range, because this is planted,laser allows to shoot bundle of tool to undertake substantially adjustment according to the requirement of material and cut task. Shoot bundle of ejaculation that direct and shoots bundle of modelling to decide to use bundle characteristic. Accordingly, a when laser process will develop henceforth main task is, use comprehensive optical device, wait for what go up in time and space to distributing to stimulating light energy, wavelengh, polarization and radiation vector the control that has just right. The ejaculation of tall trends bundle or the motion of material, can come true with scanner or direct drive technology. The newest achievement of the high speed cut that cut gas supports and the respect of remote control cut that do not have cut gas makes clear, use proper ejaculation bundle modelling and shoot bundle of control, in laminose treatment the respect can achieve unprecedented productivity (graph 5) . Current fiducial it is the laser power that uses 4kW with the board with 100m/min cut large 1mm. Graph cut of 5 remote control 0.

5mm stainless steel board the adjustment of this kind of process and move, need has comprehensive process knowledge, and these intellectual optimal means are installation is in the control equipment of the machine. Current acknowledge is to future the system puts forward corresponding key ask. The enclosed adjustment that what the sensor that borrows furtherance resembling, intelligence data processing that exceeds model support and ego optimize cut machine parameter to adjust loop, can realize this one acknowledge. This is opposite 10 new years for, for the technology that although resemble be opposite,Laser Cutting matures one kind so, also be an enormous challenge. CNC Milling
