Machine tool for precise electrical discharge machining

自2019年9月1日起，Hackert-Oschätzchen教授将担任焦点加工制造技术主席。任命Hackert-Oschätzchen教授的主要目的是扩大该主席的科学方向，将精密放电加工纳入其中。精密电火花加工是一种精密、微细加工中的烧蚀技术，适用于制造精度要求极高的工具和机械零件。在马格德堡的奥托·冯·格里克大学没有用于精密电火花加工的机床，这使得有必要采购用于精密电火花加工的机床。特别是由于与工艺相关的优点，例如加工独立于机械工件属性和无毛刺加工，精密放电加工应用于高应力部件和由高强度材料制成的产品。利用该机床可以研究精密电火花成形、精密电火花钻孔和精密电火花铣削的工艺变型。因此，除了近表面区域的微制造问题外，还可以进行宏观组件领域的研究工作，重点是精确成形，资源高效生产和功能表面。该机床适用于加工面积达600 cm²左右的部件，可以使用高达80 A的所需脉冲电流进行加工。除了研究对精密电火花加工的基本工艺理解外，资源效率技术，通过模拟进行精密电火花加工的工艺控制以及精密电火花加工数字孪生的接口和数据链将成为重点加工制造技术主席的研究重点。

The chair of manufacturing technology with focus machining is headed since on September 1st, 2019 by Prof. Hackert-Oschätzchen. With the appointment of Prof. Hackert-Oschätzchen one main intention is to expand the scientific orientation of the chair to include precise electrical discharge machining. Precise electrical discharge machining is an ablating technology in precision and micro-manufacturing, which is applied to manufacture tools and machine elements with the highest precision requirements. In the Otto von Guericke University Magdeburg there is no machine tool for precise electrical discharge machining available, which makes it necessary to procure the machine tool for precise electrical discharge machining.In particular due to the process-related advantages, such as machining independent of the mechanical workpiece properties and burr free machining, precise electrical discharge machining is applied for highly stressed components and products made of high-strength materials. By help of the machine tool, the process variants of precise electrical discharge sinking, precise electrical discharge drilling and precise electrical discharge milling can be researched. As a result, in addition to micro-manufacturing issues in the near-surface area, research work in the macroscopic component area with a focus on precise shaping, resource-efficient production and functional surfaces can also be performed. The machine tool addresses components with machining areas up to a size of around 600 cm², which can be processed with a required pulsed current of up to 80 A. In addition to researching the basic process understanding of precise electrical discharge machining, resource-efficient technologies, process control of precise electrical discharge machining through simulation as well as interfaces and data chains for digital twins of precise electrical discharge machining will be research priorities at the chair of manufacturing technology with focus machining.
