切削过程中的高温载荷会导致高刀具磨损和工件表面下区域的损伤。特别是不同切削参数之间的相互作用会影响切削区的热负荷。因此，切削过程中的温度知识是一个重要因素，也是当前研究的主要焦点。因此，本文论述了在车削过程中产生的温度的过程中监测系统。在迄今为止进行的调查相比，本研究涉及一种新的工具传感器系统的温度测量。该传感器系统通过在切削刀片的前刀面上的镍和镍铬层的PVD涂层来实现。在该层系统的接合点上，沉积有三个热电偶。涂层系统的发展和由此产生的测量。此外，与热成像系统和常规热电偶相比，讨论了结果。
High temperature loads in cutting processes can cause high tool wear and damages in the subsurface zone of the workpiece. Especially, the interaction between different cutting parameters affects the thermal loads in the cutting zone. Hence, the knowledge of temperatures in cutting processes is an important factor, and it is the main focus of current investigations. Therefore, this paper deals with an in-process monitoring system for the resulting temperatures in a turning process. In contrast to the investigations performed hitherto, this research deals with a new tool sensor system for temperature measurement. This sensor system is realized by a PVD coating of a Nickel and a Nickel–Chromium layer on the rake face of cutting inserts. On the junction points of this layer system, three thermocouples are deposited. The development of the coating system and the resulting measurement is shown. Additionally, the results are discussed in comparison to thermal imaging system and conventional thermocouples.
