使用最小直径的单刃钻孔刀具加工坚韧和高强度材料的能力并不令人满意，因为所使用的刀具非常脆且易损坏。由于对各自切削速度和进给率的更高生产率以及更高工艺安全性的相反要求，使情况变得困难。目前，必须通过昂贵的切削测试来确定每个单独应用案例的优化切削参数。斯图加特大学机床研究所对工艺参数之间的内聚性及其对控制点的依赖性进行了检查。结果输入单刃钻孔加工过程模型，该模型又为优化模型奠定了基础。通过默认条件，例如所需的加工质量、待加工的材料、加工时间等，这导致控制点的优化值，并且还为过程控制系统的应用创造了前提条件。
The machining of tough and high tensile materials with single-edge drilling tools of smallest diameter is only dissatifyingly mastered, because of the applied tools being very brittle and therefore fragile. The situation is made difficult by the opposed demands for higher productivity with respective cutting speed and rate of feed simultaniously to higher process security. At the moment, optimised cutting parameters for each individual application case have to be determined in expensive cutting tests. At the Institute for Machine Tools, University of Stuttgart, the cohesion between process parameters and their dependence on the control points are examined. The results enter a model of the machining process of single-edge drilling which in turn generates the basis for the optimisation model. By means of default conditions such as for example demanded machining quality, material to be machined, time of machining and so on, this leads to optimised values for the control points and moreover creates the precondition for the application of a process control system.
