| Abstract: | In measuring the cutting temperature by natural thermocouple method,it is important to raise the measure precision to eliminate parasitic EMF (electromotive force)of carbide blade. According to fundmental law of thermocouple, this paper advances a new method in which the draw bar is made of workpiece material for eliminate parasitic EMF. Experiments indicate that this method is possessed of accurate and convenient advanyages, it is an ideal method to eliminate parasitic EMF. |
