Kurzfassung

Machining processes are limited by tool wear caused by high thermo-mechanical stresses. These stresses are caused by the resistance between the workpiece material and the movement of the tool. Because of that the stresses occurring in machining processes are significantly dependent on the physical properties of the workpiece material. The knowledge of loads in cutting operations is important for a process design adapted to the machining task. In this research three examples of the correlation between thermo-mechanical stresses and tool wear will be presented. These examples are cylindrical turning, short hole drilling with indexable inserts and single-lip deep hole drilling.
