“…The key properties required for a temperature sensor are rapid response, small volume, high durability, and the ability to acquire the temperature distribution [33]. But the application of current contact temperature sensors is limited in cutting temperature measure due to their slow response and large volume, while the non-contact temperature sensor is greatly affected by the splashing fragmented chips under ultra high speed machining (UHSM).…”

“…This results in high temperatures in the adjoining and deformation regions of the chip, tool, and workpiece [1]. Temperature rise that inevitably occurs during machining processes causes tool wear, thermal degradation, and expansion of the workpiece, which affects the machining accuracy and quality [2]. Temperature increase in the metal cutting region softens the tool material and wears it out; subsequently, the softened tool material disperses into the workpiece material, which causes the surface finish to reduce.…”

Cutting temperature, machining parameters, workpiece material, and cutting tool geometry have a significant influence on the achievement of the desired quality of product at a satisfactory cost. The aim of the present study was to develop an empirical model for predicting temperature rise (Tr) and surface roughness (Ra) in terms of spindle speed (N), feed rate (F), axial depth of cut (D a), radial depth of cut (D r), and radial rake angle (γ). The experiment was conducted on Al 6061-T6 by using a high-speed steel (HSS) end cutter based on the central composite design of response surface methodology (RSM). A second order mathematical model in terms of machining parameters was developed. The Analysis of Variance (ANOVA) was used to study the performance characteristics in the machining process. The values of Prob>F less than 0.05 indicate that the model terms are significant. The experimental results indicate that the formation of surface defect in the end milling of Al 6061-T6 results from the re-deposited tool material, plucking, feed marks, micro-pits, and chip layer formation. The high quality of the surface texture is obtained in the combined conditions of high spindle speed, optimal feed rate, lower axial and radial depths of cut, and radial rake angle. Multi objective genetic algorithm (MOGA) has been applied to optimize the machining parameters that simultaneously minimize temperature rise and surface roughness. A set of Pareto-optimal solutions provides flexibility to the manufacturer and the process engineer to select the best setting based on the quality requirements and applications. A verification and validation process shows that the predicted values were found to be in good agreement with the observed values.

“…A type-C microthin-film thermocouple was fabricated by Werschmoeller et al [7] and diffusion bonded between two polycrystalline cubic boron nitride pieces to obtain thermal data from the close vicinity (70-700 lm) of the tool-chip interface. Recently, Sugita et al [8] used a tungsten carbide insert (WC-Co) itself as one trace of the thermocouple in order to make a micro-WC-Co and chromium temperature sensor in the trench ablated by a femtosecond laser. This study focuses on fabricating a thinfilm thermocouple inside a conventional coating system, located under the tool-chip contact area, on a commercially available WC-Co cutting insert, without the need to modify the insert in any way.…”

The objective of this work is to fabricate instrumented cutting tools with embedded thermocouples to accurately measure the tool–chip interface temperature in interrupted and continuous turning. Thin-film thermocouples were sputtered directly onto the flat rake face of a commercially available tungsten carbide cutting insert using micromachined stencils and the measurement junction was coated with a protective layer to obtain temperature data 1.3 μm below the tool–chip interface. Oblique interrupted cutting tests on AISI 12L14 steel were performed to observe the influence of varying cutting speeds and cooling intervals on tool–chip interface temperature. An additional cutting experiment was conducted to monitor the interface temperature change between interrupted and continuous cuts.
