Abstract—In simultaneous 5-axis end milling, when creating a curved surface, it is difficult to achieve consistent quality of the machined surface. However, it is known that the machine behavior changes when the approach is changed. Hence, this study aims to demonstrate the usefulness of the constant cutting point feed rate vector condition by conducting cutting experiments considering the approach. In addition, we devise a machining path to create a circle and propose an optimization method for corner tolerance speed difference. With this technique, the roundness value can be reduced by 37.2%, and a circle with a cleaner shape than the original can be machined.
Keywords—five-axis machining center, synchronous motion, shape error, higher-precision
