Looking on technical and mechanical assemblies contact surfaces mainly determine the performance of a system as they are the interfaces where energy is transferred, converted and dissipated. In the recent years functionalization of such surfaces by special manufacturing techniques became more and more important within the field of production technology. New surface conditions could be developed leading to increased performance of the entire system. This cooperative research project aims on the development of a manufacturing technique which improves the performance of cutting tools. A milling process is defined to be investigated in this project. Against the aforesaid the interfaces, which define the performance of the process, are located at the area, where interactions between tool and workpiece material take place.To reach the overall target, three scientific tasks are addressed:Development of a manufacturing technique for functionalizing the process contactsurfaces (surface modification)Development of a metrological strategy for the characterization of surface conditionsAnalysis of the addressed cutting process and determination of the influence whichthe surface modification evokesThe expected effects of the surface modification are lower friction in the chipping zone, lower tool wear, reduced energy consumption, enhanced cutting tool life time and higher applicable process velocities. For the execution of the works two research institutes from Germany and Brazil plan to cooperate in this project. While the manufacturing and metrological techniques are developed at the Houses of Production in Aachen (RWTH Aachen University/ Fraunhofer Institute for Process Technology IPT) in Germany, the process analysis and surface performance tests are conducted at Laboratory of surface phenomena LFS at University of São Paulo in Brazil. Thus the required experience and competence is available for the investigations which are settled in different scientific disciplines. The gained scientific-technological knowledge will be a comprehensive visualization of the phenomena which occur in the interface of cutting tool and workpiece material during the cutting process. This description of the phenomena will be aligned to experimental findings, which will pave the way for a technological upgrade of a broad range of cutting processes. The upgrade will be an adopted manufacturing technique for tools from many classes. The new kind of tool surfaces will exhibit the viability of reducing energy losses during the operation and thus a raise of process efficiency.

从技术和机械组件来看，接触面主要决定系统的性能，因为它们是能量传递、转换和耗散的界面。近年来，通过特殊的制造技术使这些表面功能化在生产技术领域变得越来越重要。可以开发新的表面条件，从而提高整个系统的性能。该合作研究项目旨在开发提高刀具性能的制造技术。本计画以铣削制程为研究对象。与上述情况相反，定义工艺性能的界面位于刀具和工件材料之间发生相互作用的区域。为了达到总体目标，需要解决三个科学任务：工艺接触面功能化制造技术的发展（表面改性）开发用于表征表面状态的可编程策略分析所述切削过程并确定表面改性引起的影响表面的预期效果这些改进的主要优点是在切屑区的摩擦力更低、刀具磨损更低、能耗更低、刀具使用寿命更长以及适用的加工速度更高。为了执行这项工作，德国和巴西的两个研究所计划在这个项目中进行合作。虽然制造和抛光技术是在亚琛的生产基地（亚琛RWTH大学/弗劳恩霍夫工艺技术研究所IPT）在德国开发的，但工艺分析和表面性能测试是在巴西圣保罗大学表面现象LFS实验室进行的。因此，所需的经验和能力可用于解决不同科学学科的调查。所获得的科学技术知识将是在切削过程中发生在切削工具和工件材料界面上的现象的全面可视化。对这种现象的描述将与实验结果保持一致，这将为广泛的切割工艺的技术升级铺平道路。升级将是一个采用制造技术的工具，从许多类。这种新型的刀具表面将显示出减少操作过程中的能量损失的可行性，从而提高加工效率。
