“…The thermoelectric measurement was very sensitive and could discern minute changes in temperature. The response speed is much better than the ~ 0.1 second that a thermocouple often gives (Fehrenbacher et al, 2014; Ghodam, 2014; Taysom et al, 2017).…”

“…Researchers have implemented different approaches to measure the temperature at a deforming interface, each with strengths and weaknesses. The temperature at the tool tip has been measured during cutting operations using methods such as infrared measurements through an yttrium aluminum garnet window (Heigel et al, 2017; Menon and Madhavan, 2014) and a tool–workpiece thermocouple setup (Ghodam, 2014). In friction stir welding (FSW), a nondeforming tool is rotated at the seam of materials to be joined, and the temperature at the tool–workpiece interface is of particular interest (Nelson and Rose, 2016).…”

Accurate temperature measurement is critical to understanding the thermomechanical conditions and microstructural evolution that materials experience during severe plastic deformation (SPD). Others have previously measured the interface between a non-deforming tool and metal workpiece using thermocouples, infrared measurement, and the thermoelectric principle. Measuring temperature within the deforming material itself, especially at a high-shear deforming interface, has proven to be extremely difficult, thus limiting the application of these measurements to fundamental SPD research. In this study, the thermoelectric principle is used to directly measure temperature at the interface between copper and nickel billets undergoing SPD. This is done by utilizing the deforming materials themselves as two halves of a thermocouple junction. The spatial resolution of this measurement is shown via microscopy to be less than 1 micron. Temperature changes are sensed almost instantly, with time delays on the order of the data logger frequency (0.01 seconds). Process variations that are both very brief (<0.05 seconds) and minute (<3°C) are able to be detected by this method.

“…In order to measure the cutting temperature, several techniques exist, including the tool-workpiece thermocouple, the inserted thermocouple, spectral radiation thermography and the recently proposed thin-film thermal sensor [25] [26] [27] [28]. However, these techniques cannot provide any information on the chipping, breakage and catastrophic failure of the cutting tools, nor on their service life [8] [29] [30].…”

Wear of cutting tools is a big concern for industrial manufacturers, because of their acquisition cost as well as the impact on the production lines when they are unavailable. Law of wear is very important in determining cutting tools lifespan, but most of the existing models don't take into account the cutting temperature. In this work, the theoretical and experimental results of a dynamic study of metal machining against cutting temperature of a treated steel of grade S235JR with a high-speed steel tool are provided. This study is based on the analysis of two complementary approaches, an experimental approach with the measurement of the temperature and on the other hand, an approach using modeling. Based on unifactorial and multifactorial tests (speed of cut, feed, and depth of cut), this study allowed the highlighting of the influence of the cutting temperature on the machining time. To achieve this objective, two specific approaches have been selected. The first was to measure the temperature of the cutting tool and the second was to determine the wear law using Rayleigh-Ham dimensional analysis method. This study permitted the determination of a law that integrates the cutting temperature in the calculations of the lifespan of the tools during machining.

In this paper some experimental determinations on the temperature during the turning of the pure titanium are done, using different cutting conditions. The results are presented as graphical dependencies and also as a screen capture of the values obtained using an adequate technique for registered the temperature during the turning process. Some pictures of the chips shape was captured and presented in this paper
