The requirements for energy efficiency and reduction of CO2-Emissions are growing especially within the automotive, aeronautic and power industries. One major contribution for the attainment of high requirements is the development and implementation of high performance materials. Titanium aluminides have a potential for improving combustion engines due to their low density and the constant mechanical properties under high temperatures. However, the application of titanium aluminide is limited by the high tool wear during the machining of this material. For extensive industrial utilisation of the alloy an efficient pre-shaping operation with low tool wear is required. The water jet technology is a suitable manufacturing process for difficult to machine materials, regarding the high and material independent tool life time. Through deliberate combination of radial and axial kerfs in rotational symmetric workpieces an efficient pre-shaping process could be implemented. The fundamental research in the water jet technology adds an efficient manufacturing opportunity to the cutting of titanium aluminide. First results of the research project allow the application of the procedure for rotational symmetric workpieces. Within the next research period the attainable geometric complexity of the workpiece shall be increased.

尤其是在汽车，航空和电力行业中，能源效率和减少二氧化碳排放的要求正在增长。提高高需求的一项主要贡献是高性能材料的开发和实施。铝铝材具有改善燃烧发动机的潜力，这是由于其低密度和高温下的恒定机械性能。但是，铝制铝质的应用受到该材料加工过程中高工具磨损的限制。为了大量的工业利用合金，需要使用低工具磨损的有效成型操作。水喷射技术是一个合适的制造工艺，用于难以机械材料，涉及高和物质独立的工具寿命。通过在旋转对称工件中径向和轴向kerf的故意组合，可以实现有效的预成型过程。水喷射技术的基本研究为切割钛合金的制造机会增加了有效的制造机会。研究项目的第一个结果允许将程序应用于旋转对称工件。在下一个研究期内，应增加工件的几何复杂性。
