中文摘要
近几十年来,机械加工的所有分支学科都取得了相当大的进展,例如切削过程的模拟,刀具和机床的设计,或刀具的耐磨硬材料涂层。制造技术的研发工作与摩擦学领域密切相关,特别是关于工具磨损行为的研究。在加工过程中,刀具与工件之间的相互作用具有复杂的性质,需要不同学科之间的合作来阐明它们。因此,该应用程序将使用摩擦学,涂层技术,材料科学和制造技术领域的专业知识来共同研究这个主题。特别是,重点是了解涂层工具的磨损行为作为应力谱的函数,以便能够在未来做出基于知识的工具/涂层选择,从而提高组件表面质量和工具寿命。具有几何定义切削刃的金属加工的工业标准是具有硬涂层的工具,可显着增加工具寿命。由于这种高度耐磨的涂层在加工过程中暴露在高温和滑动速度下,磨损会导致硬涂层的化学和机械变化以及复杂的摩擦学行为。今天,由于所有可能的影响变量的影响还没有完全被理解,这种行为只能通过多尺度模拟来充分描述,因此通常不允许在加工背景下对涂层刀具的磨损状况进行精确评估和预测。利用本研究工作的结果,可以预测刀具涂层在高性能pc工艺中对任何工艺参数组合和工件材料-刀具组合的适用性。这就优化了刀具的使用,减少了刀具的磨损,同时提高了生产率。
英文摘要
In recent decades, considerable progress has been made in all sub-disciplines of machining, for example in the simulation of cutting processes, in the design of tools and machine tools, or in the coating of tools with wear-resistant hard material coatings. R&D work in manufacturing technology is very closely interlinked with the field of tribology, particularly with regard to studies on the wear behavior of tools. The interactions between tool and workpiece during machining are of such a complex nature that cooperation between different disciplines is necessary to clarify them. This application will therefore use expertise from the fields of tribology, coating technology, materials science and manufacturing technology to work together on this topic. In particular, the focus is on understanding the wear behavior of coated tools as a function of the stress spectrum, in order to be able to make a knowledge-based tool/coating selection in the future that leads to higher component surface qualities and tool life. The industrial standard in the machining of metals with geometrically defined cutting edges are tools with a hard coating that significantly increases tool life. Since this highly wear-resistant coating is exposed to high temperatures and sliding speeds during machining, wear results in a chemical and mechanical change in the hard coating and complex tribological behavior. Today, this behavior can only be insufficiently described multiscale by simulation, since the effect of all possible influencing variables is not completely understood, and therefore usually does not allow a precise evaluation and prediction of the wear condition of the coated tools in the context of machining. With the results of this research work, it will be possible to predict the suitability of a tool coating for any kind of process parameter combination and workpiece material-tool combination in the HPC process. This leads to an optimization of the tool use, a reduction of the tool wear and at the same time an increased productivity.
