加工中的界面温度在刀具磨损中起着重要作用，并且还会导致工件和刀具材料性能的改变。由于环境原因，人们普遍转向干式加工，因此了解加工温度如何受到所涉及的工艺变量（切削速度、进给速率、刀具几何形状等）以及刀具磨损等其他因素的影响变得越来越重要。切削刀具在去除金属时所做的总功可以根据切削刀具上的分力来确定。大约所有这些功或能量都转化为热量，散发到切屑、刀具和工件材料中。刀具的磨损还与切削力有关。最初进行的实验涉及同时测量力和温度。这些实验的重点是使用嵌入式热电偶（在工件中）并使用红外热像仪来监控过程。 (C) 2001 Elsevier Science B.V. 保留所有权利。
Interfacial temperatures in machining play a major role in tool wear and can also result in modifications to the properties of the workpiece and tool materials. As there is a general move towards dry machining, for environmental reasons, it is increasingly important to understand how machining temperatures are affected by the process variables involved (cutting speed, feed rate, tool geometry, etc.) and by other factors such as tool wear.The total work done by a cutting tool in removing metal can be determined from the force components on the cutting tool. Approximately, all of this work or energy is converted into heat which is dissipated into the chip, tool and workpiece material. The wear of a tool is also related to the cutting forces. Initial experiments conducted involved the simultaneous measurement of forces and temperature. These experiments focused on the use of embedded thermocouples (in the workpiece) and using the infrared thermal camera to monitor the process. (C) 2001 Elsevier Science B.V. All rights reserved.
