Processes with thermo-mechanical impact in precision machining ((1) F05)

在这个子项目中，分析了未变形切屑厚度在刃口半径范围内的接触条件和机械占优载荷，以及较大未变形切屑厚度时的热机械载荷。通过切削实验和材料改性的表征，以及建模和仿真，获得了关于有效变形和切屑形成机制及其所产生的变质的知识。在这些研究结果的基础上，特别参考表面生成的动力学和增量材料体积的多重加载，导出了用于精密加工的工艺特征的几个组成部分。

In this sub-project contact conditions and mechanically dominated loads for undeformed chip thicknesses in the range of the cutting edge radius as well as the thermo-mechanical loads at larger undeformed chip thicknesses are analyzed. Cutting experiments and characterization of the material modifications as well as modeling and simulation are applied to gain knowledge about the effective deformation and chip formation mechanisms and their resulting modifications. Based on the results of these investigations, several components of the Process Signature for precision machining are derived with particular reference to dynamics of the surface generation and multiple loading of incremental material volumes.
