Machine tool for precise electrical discharge machining

2019年9月1日起，Hackert-Oschätzchen教授担任Focus加工制造技术主席。随着Hackert-Oschätzchen教授的任命，主要目的之一是扩大椅子的科学定位，将精密电火花加工包括在内。精密电火花加工是精密和微细加工中的一种烧蚀技术，用于制造精度要求最高的刀具和机械零件。在马格德堡的奥托·冯·格里克大学，没有精密电火花加工机床，这就需要购买精密电火花加工机床。特别是由于与工艺相关的优势，如加工不依赖于机械零件的特性和无毛刺加工，精密电火花加工被应用于高应力部件和高强度材料制成的产品。在该机床的帮助下，可以研究精密电火花加工、精密电火花钻孔和精密电火花铣削的工艺变量。因此，除了近表面地区的微观制造问题外，还可以开展宏观部件领域的研究工作，重点是精确成形、资源节约型生产和功能表面。该机床的加工区域可达约600平方厘米，可用高达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，资源高效型技术、通过仿真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兄弟的接口和数据链将是聚焦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.
