This thesis focuses on a systematic analysis of the cause-effect relationships between the tool stiffness and the shearing process as well as the tool wear during shear cutting with an open cutting line. Single stroke and continuous stroke experiments were conducted and the influence of selected process parameters on the forces, displacements and parts qualities was investigated. The equilibrium model of the acting forces and moments during the shearing process was extended by kinematic and elastic effects. This enables the explanation of tool wear depending on the tool’s stiffness and improves the process understanding.
