Prediction of drilling temperature during low-frequency vibration drilling of titanium alloy

Abstract: Low-frequency vibration drilling can suppress the drilling temperature and extend tool life. In low-frequency vibration drilling, there are drilling times and non-drilling times in each vibration cycle. A past study clarified that the temperature increases during drilling, and the peak temperature in one vibration cycle is nearly equal to a conventional drilling temperature, but the temperature of the drill corner decreases during non-drilling periods. However, the relationship between the amount of temperatur… Show more

“…The study showed that the simulated drilling temperature was in good agreement with the experimental results at the rising stage. However, in the dropping stage, because the friction heat, that is between the drill side and the inner surface of the hole, and the high-temperature chips accumulated in the drill flute were not considered, the simulated drilling temperature during the non-drilling period was significantly different from the experimental results [113]. When drilling CFRP/Ti stacks, Pecat et al found that LFVAD can significantly improve borehole quality compared with conventional drilling.…”

“…Extensive scholarly study has been conducted on the thermal effects produced by drilling instruments in the course of drilling operations. In their study, Okamura and Sasahara 27 conducted experimental measurements of the temperature in the vicinity of the cutting edge. They used an implanted K‐type thermocouple to accurately quantify the drilling temperature throughout both drilling and nondrilling phases of low‐frequency vibration drilling.…”

“…Many scholars have studied the heat generated during drilling. Okamura et al 19 measured experimentally the temperature near the cutting-edge by an embedded K-type thermocouple to determine the drilling temperature during the drilling and non-drilling periods of low-frequency vibration drilling. Heidari et al 20 found the cutting friction between the drill bit and the wall of hole in the process of drilling rock, which resulted in the temperature of the drill bit reaching about 500 °C.…”
