Ultrasonic-assisted technology has been found to be effective for milling Inconel 718. This study compared tool life and wear mechanisms between high-speed Ultrasonic Peening Milling (UPM) and Conventional Milling (CM) under different wear states. The analysis showed a 32.5% increase in tool life in UPM due to lower tool wear compared to CM. More importantly, UPM significantly improved surface quality and fatigue life with an average increase of 4-17 times.
Ultrasonic-assisted technology has proven effective for Inconel 718 milling. This study compared tool life and tool wear forms and wear mechanisms at different wear states in high-speed Ultrasonic Peening Milling (UPM) and Conventional Milling (CM). The influence of different tool wear states on the surface integrity index and fatigue performance were systematically analyzed. The results showed 32.5% increase in tool life in UPM owing to lower tool wear compared to that in CM. More important, UPM was significantly more effective in improving machined surface quality and fatigue life with an average increase of 4-17 times.
