Abstract
The kinematic error (KE) of a five-axis milling machine is an important measure of the accuracy. The proposed software allows to interactively position the cutter contact (CC) points to reduce the KE. The system helps to optimize the tool path by a trial and error approach and provides a learning experience for the users of five-axis machines. The code works with the STL and OFF files as well as with parametric surfaces. The Interactive system (IS) was offered to unexperienced users as a game with a goal to reduce visible kinematic errors while keeping the number of available CC points. The users were able to achieve a decrease of of the maximum KE by 91.73% and of the average KE by 43.70%. The program has been verified with a post processor from HAAS VF-2TR machining center (Trunnion VMCs).
