Stability analysis of TATWC based on UVA milling method

Difficult machining characteristics of titanium alloy materials and low rigidity thin-walled component make Titanium Alloy Thin-Walled Component (TATWC) prone to chatter during machining, resulting in poor surface quality other defects, which restricts the expansion application TATWC special industrial field. The appearance Ultrasonic Vibration Assisted (UVA) milling method provides a new technology overcome processing problems TATWC. To analyze stability processed by UVA method, first, introducing characterization function, cutting force model is established; coefficients between cutters are solved through experiments. verified comparing experimental predicted values force; Secondly, prediction based on full discrete established, effect various process parameters researched. Finally, theoretical analysis, modal measured feasibility with variable depth.
