Abstract
This article presents the results of experimental studies of tool temperature in ultrasonically assisted turning (UAT) of aerospace aluminum using Al2O3-coated tools. Temperature has been measured using K-Type Testo 735 thermocouple. The effects of work velocity, feed rate, and vibration amplitude are also investigated. These results show that UAT does not necessarily lower the cutting temperature in all cases. The effectiveness of the technique is highly dependent on the value of vibration amplitude, work velocity, and feed rate. At low feed rates and amplitude, the tool temperature for UAT is 60% of the conventional turning and it grows with increasing feed rate and amplitude.
