Cutting temperature measurement using an improved two-color infrared thermometer in turning Inconel 718 with whisker-reinforced ceramic tools
Source abstract
Abstract
Abstract Great heat will generate in turning Inconel 718 with whisker-reinforced ceramic tools. The generated great heat damages the machined surface quality. More attentions have been paid to the methodologies for accurately measuring cutting temperature in the cutting zone. However, the current methodologies of measuring cutting temperature have the disadvantages of destroying temperature field, uncertain emissivity and low measuring accuracy. In this paper, an improved two-color infrared thermometer is developed and used to measure the maximum cutting temperature in the cutting zone. The contactless measurement and the eliminated emissivity effect can improve the authenticity of the measured maximum cutting temperature. The fast response time 10 ms and the high measuring accuracy of the improved two-color infrared thermometer can meet the requirements of measuring maximum cutting temperature. The measured maximum cutting temperature increases exponentially with the cutting speed. The improved two-color infrared thermometer can be adopted to more complicated situations by moving the reliable fixed tripod and convenient focusing. The improved two-color infrared thermometer is proved to be a convenient, effective and economic methodology for accurately measuring the maximum cutting temperature in the cutting zone.
