高强度铝结构部件的新制造技术允许对材料性能进行局部修改，以响应运营需求。用于改变材料性能的加工和精加工工艺，如深轧或摩擦，应合并到一个工艺步骤中。其目的是通过修改零部件的亚表面来控制对其属性的调整。为此，有必要对车削、深轧和摩擦等基本工艺的相互作用机理有基本的了解。研究了刀具几何形状和工艺参数对材料性能的影响。这些结果将通过数值模拟中的参数研究得到扩展。此后，对工艺序列中的基本工艺的组合进行分析，以确定它们修改地下特性的能力。在此基础上，研制了一种组合式车滚刀样机。
Novel manufacturing technologies for high-strength structural components of aluminium allow a local modification of material properties to respond to operational demands. Machining and finishing processes for changing material properties like deep rolling or rubbing are to be combined to a single process step. The intention is the controlled adjustment of the component’s properties by the modification of its subsurface. For that purpose the essential understanding of the interaction mechanisms of the basic processes turning, deep rolling and rubbing is necessary. Influences of the tool geometry as well as of the process parameters on the material properties are investigated. The results will be extended by parameter studies within numerical simulations. Thereafter, combinations of the basic processes in process sequences are analyzed to their ability to modify the subsurface properties. In consideration of these results, a prototypic combined turn-rolling tool is developed
