Overview

Randomized trial compares ultrasonic vibration cutting and conventional cutting on titanium alloy machining outcomes, suggesting improved efficiency.

Key Points

  • This study aims to compare the effects of ultrasonic vibration-assisted cutting and conventional cutting on the machinability of Ti4822 titanium alloy.
  • Used a one-step in-furnace self-propagating high-temperature synthesis technique for material preparation.
  • Employed digital image correlation (DIC) for online strain distribution observation.
  • Conducted gray correlation analysis to assess the influence of process factors on machining quality.
  • Ultrasonic vibration reduces cutting force by 11.91%; maximum Y-direction strain reduction of 53.04% observed.
  • Chips transitioned from large fragments to fine strips, improving evacuation and preventing accumulation.
  • Surface roughness decreased by 54.77%, with a surface damage area reduction of 20.9%, confirmed by t tests.
