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.
