The system can be in a simple manipulator to play cut part without contact, stress-free and the circumstance that do not have pressure. Graph 1, Votan C-BIM (mobile beam of light) the system is opposite shape, cast or the plate material after drawing is done Laser Cutting and open slot. In recent years, a of automobile industry main trend is to raise the requirement of the respect such as design, function and hardware machinery intensity. This one trend is in the domain related structure and component of automobile body batholith particularly remarkable, shape under the metallic Ban gold of 2~3mm with ply for instance for complex final part. To reduce complex degree is mixed shape the cost of the tool, between a lot of case, in the manufacturing step that manufacturer decides to change a few jobs sequel. Accordingly, the job that slot opens on the spare parts or adds bore and so on is laid aside temporarily in producing a course, stay in later period to finish, obtain high accuracy thereby and won't cause machinery to be out of shape to the spare parts. More traditional production technology (if cold forging reachs punch,wait) be based on the mechanical contact between tool and spare parts. These craft can be brought while the tool uses force be out of shape and the risk of attaint workpiece. In addition, the automation of this kind of craft needs to contain very firm the force outside be absorbed with the manipulator system of tall stability. Another kind of choice is water efflux, it has a lot of advantages, offerred a kind of reliable technology program. Its defect depends on: The need after cut ends undertakes to workpiece dry, cut speed is finite, and need pair of work, especially workpiece brim part, undertake cleanness. The additional solution that simple manipulator system provides perspective one kind quite is Laser Cutting coordinates simple manipulator system. What this plan offerred height is flexible and without cut of osculatory high speed, won't generate the mechanical stress to workpiece or pressure. In addition, it makes stimulate beam of light to be able to process more data, high power density means the hot impact near cut mouth the area is very small, of spot dimension small (be less than normally 0.

3mm) the cut width that makes its can cut a minimum. Express the 1 pandect that offerred cut of efflux of pair of punch, water and Laser Cutting. Graph 2, use 2.

The typical rate when 5kW CO2 laser has cut (this graph origin: Rofin-Sinar company) laser work skill by compositive mix reliably to height the industrial circuit that can dog, it is the main factor that its regard a kind of tool as to score a success. The market needs low investment especially cost and have reasonable move reach the plan that defends cost. Likewise important still have simple effective however technology, have Gao Rou sex at the same time, differ with getting used to production quickly, new product. After fulfilling these premise requirements only, laser ability is thought shape in cut Ban gold the respect is a tool that has an advantage. One kind guides with the manipulator that stimulates beam of light at shift those who brought plan to add whole system is flexible the physical ability with the system, make its can machine the part that 5 shaftings all is hard to handle common dragon door. In addition, this plan still was offerred taller flexible with the method of simple process designing that stimulates beam of light. The crucial success that stimulates beam of light to deliver will stimulate beam of light compositive the character that depends on stimulating beam of light to deliver itself to the key of manipulator system. A kind of traditional plan is to use solid state laser to be the same as fiber-optic coupling, use manipulator to undertake guiding bringing next, make its reach the working place of the requirement. The defect of this plan depends on low radius of bend and fiber-optic inside reflection can restrict his flexible with dependability, bring damage thereby. Contrast to it, CO2 stimulates beam of light to have quality of higher beam of light, small focusing area normally, and the close gauss density around laser focus distributings. Accordingly, cut width is very small (it is only normally 0.

1~0.

3mm) . In addition, the investment of CO2 laser and moving cost under solid state laser. It is as a result of the working wavelengh of CO2 laser 10.

6 M, because this is impossible to use glass fiber-optic will guide leave beam of light, can use however guide smooth lens will finish. Be able to succeed in the 3 shaftings interconnected system that this method has used in 2 dimension use, use the lens that has installed beforehand to will stimulate reflex of beam of light to form smooth way. In the past, the design train of thought of system of inchoate manipulator CO2 laser is as follows: There is the lens that is used at delivering to stimulate beam of light in the outfit inside exterior manipulator, make laser delivers laser head from laser. This manipulator itself is guided bring by a manipulator (the 6th axis) , the freedom that reduced whole system thereby moves. Another development achievement is to design the laser system that has power of the biggest output to amount to 2 kilowatt, the laser in this system is by installation on the axial of manipulator, stimulate beam of light to be passed to laser head through specific lens. Between this one concept, complete laser source is in whole in moving, be carried on manipulator, its load is 250~300kg about. This restricted the dynamic function of motility, precision and system apparently, and to high speed next precision when completing course of more sophisticated treatment brought negative effect. The life that this reachs its system to laser likewise and safeguard a requirement to cause negative effect. The smooth region with compositive and whole Nextpage is in company of Jenoptik automation technology, the system of laser of new generation CO2 that is based on manipulator has been born (its character sees a table 2) , its laser power can be as high as 5000W, and have more high accuracy and dynamic function. In this system laser is the same as manipulator depart with mechanical means. Pass the collaboration with St Ubli company, stimulate beam of light to be able to be linked together with manipulator bottom with optical means now, thereby will complete laser Shu Guanglu is compositive to laser head most advanced. Specifically, stimulate beam of light to pass the lens that is in nicety to secure in manipulator axial turning point, be directed come the front of manipulator, next by focusing, conveyed to equip the cut head of switch and cut gas nozzle. Because this one new idea is adjustable lens and become a possibility, these lens are used at by the design compositive the articulatory place that takes manipulator. Besides, all lens must use water-cooling refrigeration, the laser that allows to deliver power to be as high as 5000W thereby bundle. Destroy to prevent particle to arise to lens, a complete set of guides smooth component is being protected by a directional pipeline system (see a picture 1) . CO2 laser smooth road by compositive in manipulator, the return loss in whole smooth road is little at 5% . Graph 2 showed system of mobile beam of light of a Jenoptik C-BIM is mixed 2.

5kW CO2 laser combines brought typical case to machine speed. Its test and verify plate thickness is in under 3~4mm (the data that no less than uses in automobile body structure in that way) when, the implementation in can opening groove and cut treatment is more than 4m/min, highest 14m/min (cut stainless steel) high speed treatment. According to this one design, manipulator maintained comprehensive precision and trends specific, and weight is very light (about 150kg) , because this high accuracy locates,ask (+ / - 0.

1mm) can achieve when cut metal spare parts. We can conclude, jenoptik developed a kind to be used at conducting CO2 to stimulate beam of light and the principle is similar at guiding fiber-opticly optical system, usable Yu Gaogong leads region. This solution represented a kind to have perspective and reliable technology, can replace system of solid state laser with lower cost, do not be cost with sacrificial application function at the same time. Graph 3, provide CO2 laser system and compositive the laser beam machining of manipulator (cut) unit systematic concept (most high-power 5kW) . The firm of compositive technology Jenoptik that is used at industrial practice further, mix manipulator, laser cooling device is compositive go up in a platform, realize compact treatment unit, satisfy industry to fulfil medium requirement thereby. Graph in 3 indication solutions, of workpiece go up to carry and move to pass revolving stage coming back to finish, laser system, filter the back end that device is located in treatment unit etc. It is very easy to should machine unit itself to regard an independence as odd potential energy be moved, and need not adjust too much beforehand. The dimension of typical spare parts that it machines most greatly 500mm of × of 1400mm × 700mm, its whole dimension is about respectively 5.

30m (power is more than 600W model) . Another kind of means passes conformity a two manipulator, laser and a spectroscope or two laser process unit at inside, use at treatment large, complex with difficult treatment spare parts, among the application that perhaps has demand of inferior cycle time. These compact concept structures are had tremendous flexible, need for those flexible cut system, the company that completes much breed, high quality in order to repeat to process business brought first-rate solution. Conclusion is latter the trend of cut flow automation, especially the tendency that three-dimensional treatment way develops, to automation treatment company posed a challenge. High accuracy and cut of flexible, high speed, be based on demand guide smooth concept and reasonable investment cost, adding the characteristic such as compact design is the focus that people pays close attention to. What Jenoptik company brings is one kind can satisfy all laser systems of these requirements, offerred a kind of agile and feasible program to replace existing Laser Cutting system.
