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.

在该子项目中，分析了切削刃半径范围内未变形切屑厚度的接触条件和机械主导载荷，以及较大未变形切屑厚度下的热机械载荷。切削实验和表征的材料修改，以及建模和仿真，以获得知识的有效变形和切屑形成机制和由此产生的修改。基于这些调查的结果，精密加工的过程签名的几个组成部分，特别是参考动态的表面生成和多个加载的增量材料体积。
