Apply to dynamic cutting " VITAMIN CFRP "

Fulaoenhuofu produces technical institute (the researcher of I PT) is engaged in overall structure optimizing research. The whole structure that their job is aimed at a machine tool -- include important drive part. At present they are cooperating with the MAP Werkzeugmaschinen company of German Magdeburg, the new-style carbon fiber that considers to be used at perpendicular motion enhances composite material (spare parts of CFRP) machine tool, and the installation that how optimizes axle sleeve canister, latter is the key of this second research. This project will produce technical institute to exhibit in the Fulaoenhuofu of EMO Hannover 2017 on showpiece. Light simple stuff introduces machine tool industry successfully: The sleeve of axis of machine tool Z that carbon fiber enhances composite material and metal to mix material to be made is balanced function and heavy " carbon fiber enhances canister of composite material axle sleeve to began to develop 2013. " the spot director Christoph Tischmann of MAP is recollected, "For example, in machining aluminous goods process, accumulated rich linear and experience of runner shaft coming back. But to high strenth material character, for example titanium alloy, chromic ferronickel alloy, its function experience still is existing to be not worth. " accordingly, MAP decides to develop a machine tool that has powerful driver. Accordingly, mix in S1 now S6 in unit process of cargo bandling, use the main shaft of 55 KW and 72 KW respectively, the torque of M of 210 N · and M of 273 N · , but these equipment are very heavy, volume is larger also. "Allow why to be affected to make sure motivation does not get, we hope to seek the way that amends greater weight. " Tischmann explains, optimal method should be to use pledge gently and solid carbon fiber enhances composite material, previously, the machine tool that cooperates to use with box of canister of Z axle sleeve can provide the power of 28 ～ 36 KW. Accordingly, in this give typical examples, can enhance drive power double the left and right sides. Meanwhile, relatively at stainless steel axis, use carbon fiber enhances composite material, can reduce weight 60% the left and right sides. "But, our target is not to achieve some target weight, want to obtain optimal balance relationship between weight and stiffness however. " the technician Filippos Tzanetos that Fulaoenhuofu produces technical institute tells us. Next the problem is: After changing stainless steel sleeve to strengthen composite material structure for carbon fiber, drive power promotes double. For this, fulaoenhuofu produced technical institute to analyse whole equipment to cover the hot reaction between the canister and dynamic reaction to Z axis. "Undertook to equipment from in the complete test outside arriving. " Tischmann points out. On these bases that measure parameter, made a few kinds of equipment choose a solution, in order to improve facility construction. Manufacturing technology institute and Lerinc company combination developed Fulaoenhuofu to use the 5 axes machine tool that provides carbon fiber to enhance canister of axle sleeve of composite material drive. Not only the structure is strong, and still have the acceleration that makes a person impressive can, this one equipment still can be processed place to need appearance material to because this are new-style,decide a structure material cannot arrive with man-to-man means is joined simply in existing structure, this the task is to use most appropriate material structure, the test and verify in applying actually is finite yuan of imitate. "On the computer, we checked to produce the characteristic of metabolic area structure the most easily, so that we find a reason. " Tzanetos explains. Next, researcher tries to use the component before aluminium makes a part or carbon fiber enhances composite material spare parts to change, or through installing consolidate lever or consolidate material, in order to raise the dynamic character of certain position. Use carbon fiber enhances composite material to designing an engineer character is a grim challenge, because material has anisotropy: According to the definition, anisotropy is to show the property that comes out now in system of the place on each direction is different. This is meant when handling fiber material, stiffness or intensity depend on fiber direction. But carbon fiber enhances composite material the character in imitate and actual condition is not same. Tzanetos explains in detail: "According to DINISO 21748: 2014-05, can use patulous uncertainty to determine simulative effectiveness. Because the uncertainty of model parameter is met,the output variable to the model produces certain effect, and use Monte Carlo simulation when, this kind of uncertainty can be accumulated. " carbon fiber enhances composite material and aluminium to make canister of Z axle sleeve joins between flange the close-up of area, latter is the essential component that makes component part milling machine category eye is here medium, the institute connects Fulaoenhuofu to often can accept the help that other orgnaization or subsidiary provide. But, in this case, the scientist obtained the help that he belongs to an orgnaization. "In our orgnaization, set composite material of a fiber and laser system Technical Division. " Tzanetos expresses. Old since, this branch already had enough actual strength, can increase according to fiber plastic (component of FRP) design machine tool, and can ensure project group understands technology of its imitate major. The ability that bind can ensure the success supports this kind plastic to replying to use FRP(fiber to increase in machine tool and safe structure) the pertinent question of package very important, because these machine material to have the physical characteristic with independent direction, the chance that collides so is less. "Before, fiber of existence limitation use FRP(increases plastic) regulation, because do not have any structures that can draw lessons from and design standard, because this cannot forecast FRP(fiber well and truly directly,increase plastic) how does package undertake with the other component of machine tool structure trends interacts. " researcher explains. Composite material and the stiffness that if package adopted only way only,plastic technology edits personnel Peter Königsreuther are designed, and the stiffness that did not consider other axis is characteristic, with respect to meeting occurrence mistake. "But, if we let FRP(fiber increase plastic) package and machine tool are achieved between dynamic component and simulation tool perfect match, appear almost unlikelily any mistakes. " Tzanetos emphasizes. Accordingly, technical institute is produced in Fulaoenhuofu in, this is this project most the problem that is badly in need of solving. The main reason that uses fiber composite material in machine tool structure is, if why dug increases in carbon fiber firm felt undertakes between composite material and metallic component. Narrate according to Tzanetos place, before, this depends on special sizy technology, but such meeting brings a lot of issues: ■ must enhance composite material surface to undertake mechanical processing to carbon fiber. This will bring about carbon fiber to enhance composite material character inhomogenous, change its character; infirmly ■ the strength that gelatinize place generates is lesser (every union place is only between 10 ～ 40 Mpa) ; ■ felt quality basically depends on environmental parameter, for example temperature, have content of free from contamination, hub and use cooling fluid; ■ glue is stuck receive place wear away faster. Tzanetos say, can eliminate these defect for example through using laser technology. But the problem that Tischmann of MAP decision-making personnel saw join technology exists not only, return say: "Repeat accuracy to ensure the exact location of the machine tool is mixed, even if in high trends treatment status falls, we also can make sure the support of attrition linear slideway serves. " to MEP, use carbon fiber to enhance composite material to arrive at this one precision to also existing now very big challenge. EMO Hannover 2017 -- the source Tishman say of innovation inspiration, although existing these block up, but consider EMO Hannover 2017 hold, carbon fiber enhances composite material or be worth to try. Machine tool manufacturer considers to use Fulaoenhuofu to produce the associated information warehouse of technical institute, can reveal this among them brand-new the advantage that processes data and regulations. "In principle, when this project ends, we can permit dynamic, choice and the machine tool throw on the market with powerful function. " later, application can be built in aviation domain. the scientist that produces technical institute to Fulaoenhuofu, with the project of this kind of job that MAP Werkzeugmaschinen develops, opened new entrance door to begin communication with the industry. The project that developing currently will be encouraged inferior treasure group and trade partner together, continue to lead carbon fiber to enhance the development of composite material domain. To attending EMO Hannover2017, tzanetos and the colleague hope that come from industrial domain can be exhibited in this on the meeting, pledge gently new breakthrough place is found on the similar problem of structural material.
