Abstract: The machining of titanium alloys classified as difficult machining materials. It is a major problem how to improve the machining efficiency of titanium alloys. The TC4 and YS8 natural thermocouple pair was calibrated and the variation of electromotive force with change of temperature was obtained. The calibrated results were used to measure the cutting temperature while machining TC4 and the variation regulation of cutting temperature with cutting speed was obtained.
