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.

对能源效率和减少二氧化碳排放的要求日益增长，尤其是在汽车、航空和电力行业。实现高要求的一项主要贡献是高性能材料的开发和实施。钛铝化物由于其低密度和高温下恒定的机械性能而具有改善内燃机的潜力。然而，铝化钛的应用受到该材料加工过程中刀具磨损较高的限制。为了在工业上广泛利用该合金，需要进行有效的预成型操作并降低工具磨损。水射流技术是一种适合难加工材料的制造工艺，具有较高的且与材料无关的刀具寿命。通过在旋转对称工件中精心组合径向和轴向切口，可以实现高效的预成形过程。水射流技术的基础研究为铝化钛切割提供了高效的制造机会。该研究项目的第一个成果允许将该程序应用于旋转对称工件。在下一个研究期内，工件可达到的几何复杂性将得到提高。
