当在汽车工业或其他工业应用中使用调质钢时，疲劳性能至关重要。加工零件的表面和亚表面完整性被认为是与零件疲劳强度相关的关键因素之一，并且受到加工工艺的强烈影响。特别是对于深孔单唇钻削，很大一部分切削力传递到孔壁，并且表面和亚表面区域受到刀具和工件材料之间相互作用的影响。在本研究中，详细研究了向孔壁插入残余应力并以某种方式影响孔亚表面微观结构的方法，使部件能够承受更高的机械和动态载荷。在作者的密切合作下，单唇钻孔工艺和工件材料的参数与所产生的表面质量和表面下微观结构以及由此产生的部件疲劳强度相关。为了比较表征疲劳行为，已建立的破坏性材料测试程序与新的无损测试方法（例如巴克豪森噪声分析）相结合，得到进一步应用和发展。疲劳测试的结果与巴克豪森噪声分析的结果相关，用于设计一个模型来预测钻孔部件的疲劳强度。
When using quenched and tempered steels in the automotive industry or other industrial applications the fatigue behavior is of elementary importance. The surface and subsurface integrity of machined parts is known as one key factor related to the fatigue strength of components and is strongly influenced by the machining process. Especially for the deep hole single lip drilling, a large part of the cutting force is transferred to the bore wall and the surface and subsurface zone are influenced by the interaction between the tool and the workpiece material.In this study, the approach of inserting residual stresses into the bore wall and influencing the microstructure of the bores subsurface in a way, that the components can withstand a higher mechanical and dynamic load, is investigated in detail. In a close cooperation between the authors the parameters of the single-lip drilling process and the workpiece material are correlated with the produced surface quality and subsurface microstructure as well as the resulting fatigue strength of the components. For the comparative characterization of the fatigue behavior, established test procedures of destructive material testing in combination with new non-destructive test methods, such as the Barkhausen noise analysis, are applied and developed further. The results of the fatigue tests in correlation with the results of the Barkhausen noise analysis are used to design a model for predicting the fatigue strength of drilled components.
