Horizontal 5-axis machining centre

能源生产领域的新概念和航空领域资源效率的持续提高越来越需要研究工艺链，以生产大型同时非常精密的部件，如大型齿轮、结构部件或涡轮机械部件。多年来，加工由难加工材料制成的部件和精度要求最高的部件一直是RWTH亚琛大学WZL的研究重点。然而，这项工作的基本发现不能轻易地转移到大型机器和上述领域的较大部件的加工上。其中一个原因是加工这些部件时的机械、热和动态工艺特性，这些特性通常与部件尺寸不成线性关系，因此无法从较小的部件放大。对于大型部件生产中的工艺优化，还必须考虑大型机器的技术系统，与小型机器相比，大型机器具有独特的性能。例如，大型机器，如部件，由于其更大的质量、更高的自然频率、更大的驱动功率、不同的设计、运动学和更长的旅行距离，具有根本不同的热、机械和动态行为。然而，他们必须在显著更高的切割速度下，在个位数的微米范围内达到类似的精度要求。这种行为只能在大型机器的基础上进行研究，尤其是在具有普遍而深远的性能谱的机器上。该提案遵循以下论点：第三章为各个工作组列出了未来几年将开展哪些与大型零部件制造和五轴大型加工中心有关的研究项目。在这些研究项目的基础上，得出了可量化的机器特定要求，并给出了为什么某些机器特性是必要的原因。最后，在第四章中，从技术层面上从可供选择的机器中描绘了最受欢迎的机器配置，从而阐述了其相对于需求集的唯一性。

New concepts in the field of energy generation and the consistent increase in resource efficiency in the field of aviation increasingly require research into process chains for the production of large and at the same time very precise components such as large gears, structural components or turbomachine components. The machining of components made of difficult-to-machine materials and components with the highest precision requirements has been a focus of research at the WZL of RWTH Aachen University for many years. However, fundamental findings from this work cannot be easily transferred to large machines and the machining of larger components from the areas mentioned. One reason for this is the mechanical, thermal and dynamic process properties when machining these components, which often do not behave linearly to the component size and accordingly cannot be scaled up from smaller components. For process optimisation in the production of large components, the technological system of large machines, which has unique properties compared to smaller machines, must also be taken into account. For example, large machines, like the component, have fundamentally different thermal, mechanical and dynamic behaviour due to their larger masses, higher natural frequencies, increased drive power, different designs, kinematics and increased travel distances. Nevertheless, they have to achieve similar accuracy requirements in the single-digit micrometre range at significantly higher cutting rates. This behaviour can only be investigated on the basis of a large machine, and in particular on one that has a universal and far-reaching performance spectrum. The following line of argument is followed in the proposal: Chapter 3 sets out for the individual working groups which research projects related to large component manufacturing and 5-axis large machining centres are to be carried out in the next few years. Based on these research projects, quantifiable machine-specific requirements are derived and reasons are given as to why certain machine characteristics are necessary. Finally, in Chapter 4, the favoured machine configuration is delineated from alternative machines on a technological level and thus its uniqueness in relation to the requirements set is elaborated.
