| Popis: |
Manufacturing of monolithic aerospace components entails development of complicated 5-axis tool paths containing thousands of lines of code and dozens of tool changes for milling and drilling operations. In-cut machining cycle times of 50-100 hours are common. Achieving meaningful reduction of cycle time while maintaining part quality is predicated upon the ability to model the physics of the machining operations. A methodology to predict forces used for analyzing large, complicated 5-axis tool paths for aerospace component machining is presented. The ability to accurately model length scales from the chip load (~100 microns), part thickness (~2mm), depths of cut (~10mm) to part dimensions (~10m) is provided. Forces and temperatures are predicted over the entire tool path using analytical and numerical techniques to extend an empirical database to generalized cutting conditions. Using the same model, a method to achieve tangible reduction in cycle time without affecting part quality is presented. |
