Based on the specific demands from die- and toolmaking industries, 5 axis milling strategies ensuring high manufacturing accuracies must be realized. The machine development of the hexapod prototype is focused on homogenous inclination of the HSC spindle inside the workspace, suitable strut load characteristics, joints free of clearance and a special HSC control providing the necessary accuracies at high feed rates by compensation algorithms. Due to suitable tool positioning to the part and higher path speed values when milling sculptured surfaces, the hexapod prototype has a lot of advantages against miscellaneous machines.
