Abstract

Computer aided NC-path generation of five-axis milling using a standard CAM-system does usually not take machine dynamics and kinematics into account. This results in machine movements which are often not smooth enough and lead to a deficient surface quality. In order to reduce undesirable abrupt motion changes, an approach for optimizing the NC-path by using a standard evolution strategy is shown in this paper as well as first results of applying this algorithm to the five-axis milling process.
