  • The effect of cutting vibration on tool wear in cutting titanium alloy Ti-6Al-4V with CBN tool was studied.By using finite element analysis technology, orthogonal experiments were designed to analyze the effects of vibration amplitudes and frequencies in different directions on tool surface stress and tool temperature, so as to study tool wear under cutting vibration conditions.The results of finite element simulation showed that the influence of X-direction vibration on the stress and temperature of the tool surface was limited.There was no obvious regularity.The wear of the tool was not aggravated by X-direction vibration condition.The influence of Y-direction vibration on the stress and temperature of the tool surface was greater.The stress and temperature of the tool surface increased with the vibration amplitude and frequency in Y-direction.When the vibration occurred in both X and Y directions, the stress and temperature on the tool surface increased with the increase of vibration amplitude and frequency, which was characterized by severe tool wear.Cutting experiment was carried out.It was found that the vibration had a great influence on the tool wear, which was basically consistent with the results of the finite element analysis.
