最近，出现了对新的加工在线技术的需求，以监控和/或控制加工系统。由于数字热敏非接触相机的引入，因此有可能评估芯片温度，从而评估边缘性能与这种温度范围内变化之间的可能关系。非接触式红外热像仪安装在车床托架上，用于记录在使用涂层和非涂层硬质合金刀片时，随着切割速度和进给量的变化而产生的切割温度。分析了温度梯度和相应的扫描电子显微镜照片与规则和不规则刀具刃口变形的可能相关性。虽然切割速度被证明不是影响所描绘的温度的参数，但进给量的增加往往会降低切割温度。通常，可以观察到，当使用涂层插件时，产生较低的热量和温度。结果表明，随着刃口磨损和变形的发展，切削温度逐渐升高。
Recently, the need arises for new machining inprocess techniques to monitor and/or control machining systems. Due to the introduction of digital thermal noncontact cameras, it becomes possible to assess the chip temperature hence, to evaluate the possible relation between edge performance and variation within such temperature. A noncontact infrared thermal camera is mounted on a turning lathe carriage to record the cutting temperatures as cutting speed and feed vary using both coated and uncoated carbide inserts. Temperatures gradient, along with the relevant SEM micrographs, are analyzed for possible correlation with both regular and irregular cutting edge deformation. While cutting speed proved not to be an influential parameter on the depicted temperatures, feed increase tends to lower cutting temperatures. Generally, it is observed that lower heat and temperatures are generated when coated inserts are employed. It is found that cutting temperatures are gradually increased as edge wear and deformation develop.
