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，越来越多地要求研究生产大型精密部件（如大型齿轮、结构部件或涡轮机械部件）的工艺链。亚琛工业大学WZL多年来一直致力于对难以加工的材料和精度要求最高的部件进行加工。然而，这项工作的基本发现不能轻易地转移到大型机器上，也不能从上述领域加工更大的部件。其中一个原因是加工这些部件时的机械、热和动态过程特性，这些特性通常与部件尺寸无关，因此不能从较小的部件按比例放大。为了优化大型部件的生产过程，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，如组件，由于其更大的质量，更高的固有频率，增加的驱动功率，不同的设计，运动学和增加的行驶距离，具有根本不同的热，机械和动态行为。然而，他们必须在明显更高的切割速率下，在一位数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，特别是在具有通用和深远性能谱的机器上。在建议中，论点如下：第3章为各个工作组列出了在未来几年内将进行的与大型部件制造和五轴大型加工中心有关的研究项目。基于这些研究项目，导出了可量化的机器特定需求，并给出了为什么需要某些机器特性的原因。最后，在第4章中，从技术层面上描述了优选的机器配置，从而阐述了其与需求集相关的独特性。

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.
