Kurzfassung

Generating five-axes NC-paths by a standard CAM-system still contains many problems, especially concerning the simultaneous movements of all axes of a given machine tool. These movements are often not smooth enough and lead to unwanted jerks resulting in a poor quality of the workpiece surface. In order to reduce this effect, two different algorithms are introduced in this paper. First approaches of optimising the machine kinematics by using a standard evolution strategy are presented as well as the integration of these algorithms in a simulation environment for five-axes milling processes.
