hi ... A good racing car can not be separated from the design and building design body car .. the weld body has a high ..Many aircraft components are made by mechanically fastening subcomponents together or by machining them with numerical control from a solid material.
One major problem with mechanical fastening is it suffers from corrosion and numerical-controlled machining is considered to be a wasteful process in terms of time, energy and raw material. Ibáñez said this is because a typical aluminium aeronautical part is composed of many cavities and the walls between these cavities are often very thin. A numerically controlled machining process will take a long time to machine a complex shape from a single aluminium plate.
'The process is time-consuming and it generates a lot of chips,' which are the wasted metal bits machined off the original part, she said. 'More or less chips represent 95 per cent of the weight of the whole part.'
The Fatronik-Tecnalia manufacturing process would use simpler, individual parts created by machining, stamping and incremental sheet forming. The process involves shaping a metal blank by a CNC-driven small-size punch.
These individual parts would then be joined together in Fatronik-Tecnalia's friction stir welding machine. Fatronik-Tecnalia claims this entire manufacturing process will produce 70 per cent less metal waste compared to machining a part from a solid material.
Ibáñez said the Fatronik-Tecnalia friction stir welding machine could be used to create aeronautical parts such as wing panels, fuselages and fuel tanks. The centre would also be interested in promoting its machine to the automotive and railway sectors. Two Spanish companies — bus and coach manufacturer Irizar and rail stock specialist CAF — have already expressed interest in the Fatronik-Tecnalia machine.
The centre developed its machine as part of the EU-funded NEXT (Next Generation Production Systems) project. Other collaborators on the project, such as Ona Electroerosión, a Basque manufacturer of electrical discharge machines, have developed new formulations for the liquids and filters of production machines to render them self-cleaning and less contaminating.
Another project collaborator, Spanish machine tool manufacturer Danobat, recently unveiled an 'ecological' grinding machine that reduces the use of refrigerant liquid by 80 per cent and energy consumption by 50 per cent.
