This project proposes to develop and improve concurrent technologies on producing precision EDM electrodes by Layer Manufacturing Technique (LMT) to Electro-Discharge Machining advanced 3D products. The project workplan consists of 5 workpackages (WP) to be executed in 2 years (2009-2011). The electrodes will be manufactured with different materials using LMTechnique based on Laser sintering via IMW-TUClausthal facilities. The necessary powder material blends will be obtained using powder metallurgy know-how from the ZFW-TUClausthal. The assessment and improvement of EDMachining performance measures will be in charge of LAUS-PUCPR. The partners’ collaborative work will enable the specification of electrodes geometries and materials applicable for precision EDMachining The expected outputs are the electrode performance correlating EDMachining and LMT variables, the specification of adequate materials and postprocessing e.g. coatings for LMT-EDM electrodes, the development of EDM technology tables and procedures for design and fabrication of precision electrodes and an envelope with adequate process EDM parameters settings. The project results will be tested on a real industrial application of a particular electrode geometry using an adequate EDM procedure. This proposal is inserted into the agreement reached on July of 2007 between Technische Universitaet Clausthal - TUC and Pontifícia Universidade Católica do Paraná – PUCPR and as well as into the strategic interest of the BRAGECRIM Program. The sustainable development of the German-Brazilian production chain through innovative technology is considered in this project. The project will not only be an opportunity to manufacture EDM electrodes, but also to establish a communication channel for technology and human resources transfer between TUClausthal and PUCPR linked to the Brazilian/German industries.

本项目拟开发和改进利用层加工技术（LMT）生产精密电火花电极的并行技术，以电火花加工先进的三维产品。项目工作计划包括5个工作包（WP），将在两年内（2009-2011年）执行。电极将通过IMW-TUClausthal设备使用基于激光烧结的lmtechnology制造不同材料。使用来自ZFW-TUClausthal的粉末冶金技术，将获得必要的粉末材料混合物。EDMachining performance measures的评估和改进将由LAUS-PUCPR负责。合作伙伴的协作工作将使适用于精密EDM加工的电极几何形状和材料的规格成为可能。预期的输出是与EDMachining和LMT变量相关的电极性能，适当的材料和后处理的规格，例如LMT-EDM电极的涂层，用于设计和制造精密电极的EDM技术表和程序的开发，以及具有适当工艺EDM参数设置的外壳。项目结果将在实际工业应用中使用适当的电火花加工程序对特定电极几何形状进行测试。这一建议被纳入了2007年7月德国工业大学-德国理工大学和Pontifícia universitade Católica do paran<e:1> - PUCPR之间达成的协议，以及BRAGECRIM计划的战略利益。该项目考虑了通过创新技术实现德国-巴西生产链的可持续发展。该项目不仅是制造电火花加工电极的机会，而且还将为TUClausthal和PUCPR之间与巴西/德国工业相关的技术和人力资源转移建立沟通渠道。
