... presents a novel approach to obtain transient tool internal temperature data reliably from a very close distance to the tool-workpiece interface. An array of nine microthin film thermocouples, fabricated using standard microfabrication methods, has been embedded into polycrystalline cubic boron nitride...

...Bin Shen; Guoxian Xiao; Changsheng Guo; Stephen Malkin; Albert J. Shih A new thermocouple fixation method for grinding temperature measurement is presented. Unlike the conventional method using a welded thermocouple, this new method uses epoxy for affixing the embedded thermocouple within a blind...

... and close to the region of the interaction. Moreover, C-type micro thin film thermocouples with a junction size of 2 × 2 μ m 2 were fabricated to increase the maximum operation temperature and spatial resolution of sensors. Surface temperature distribution around the laser spot was obtained in the range...

... in terms of the reduction of cutting temperature through the cooling effect, as well as the reduction of heat generation through the lubricating effect. To pursue model calibration and validation, embedded thermocouple temperature measurement in cutting medium carbon steels with uncoated carbide insets...

...-film thermocouple system has been established for measuring instantaneous workpiece temperature in chemical explosive material machining. The thin-film thermocouples have been directly deposited inside high-speed steel cutters by means of multiple arc ion plating and the thickness of the thermocouple...

... suitable for a workpiece with low cross section Biot number. Induction heating experiments are carried out using a carbon steel rod. The finite difference method and thermocouple temperature measurements are applied to estimate the induction heat flux and workpiece temperature. Compared to measured...

...Matthew Bono, Graduate Student; Jun Ni, Professor A drill-foil thermocouple system is developed for measuring the temperature distribution along the cutting edges of a drill. The system is simple to implement, and it does not suffer the problems experienced by previously developed methods...

... for estimating the energy partition in grinding. Grinding temperatures were measured in the workpiece subsurface under identical surface grinding conditions using an embedded thermocouple and a two color infrared detector, and on the workpiece surface using a foil/workpiece thermocouple. All three methods gave...

...M. H. Attia, Fellow ASME Adjunct Professor,; A. Cameron, Research Assistant; L. Kops, Fellow ASME The main objective of this investigation is to develop a model for predicting the systematic temperature measurement error due to the thermal disturbance in the region surrounding the thermocouple hot...
