“…These restrictions allowed the development of an additional method to determine temperatures with thermocouples called the tool-work (tool-chip) thermocouple or dynamic thermocouple. This technique was used by Alvelid [15], Stephenson [16], Lezanski et al [17] or Groover et al [18]. With this method, the entire tool is used as a part of the thermocouple and the workpiece as the other part.…”

Cutting temperature and heat generated at the tool-chip interface during high speed machining operations have been recognized as major factors that influence tool performance and workpiece geometry or properties. This paper presents an experimental setup able to determine the temperature field in the cutting zone, during an orthogonal machining operation with 42 CrMo 4 steel. The machining was performed with a gas gun, using standard carbide tools TiCN coated and for cutting speeds up to 50 ms -1 . The technique of temperature measurement was developed on the principle of pyrometry in the visible spectral range by using an intensified CCD camera with very short exposure time and interference filter at 0.8 µm. Temperature gradients were obtained in an area close to the cutting edge of the tool, along the secondary shear zone. Effects of the cutting speed and the chip thickness on the temperature profile in the chip were determined. Maximum chip temperature of about 825 °C was found, for cutting speed close to 20 ms -1 , located at a distance of 300 µm of the tool tip. It was established that this experimental arrangement is quite efficient and can provide fundamental data on the temperature field in materials during orthogonal high speed machining.

“…This means that the two sensors are exactly embedded at the same location with respect to the tip of the drill and the revolution axis. Therefore, this leads to the following relations: [11] k = α [22] k , α [12] k = α [21] k β [11] k = β [22] k , β [12] k = β [21] k ,…”

“…Stephenson [8] and Stephenson and Ali [9] measure the temperature in the workpiece by IR thermography and use the analytical solution of heat transfer in the workpiece to estimate the temperature in the shearing zone. Groover and Kane [11] embed two thermocouples in the tool holder. A model that expresses the average temperature on the cutting edge and the temperature at these two thermocouples is achieved by a nodal method based on the thermoelectric analogy.…”

Heat fluxes on each cutting edge of a carbide double cutting drill are estimated during a high-speed machining process from temperature measurements in the drill tool and a direct model that has been established using the non integer system identification approach. A single experiment is required in order to characterize the transient thermal behavior of the tool. The non integer system identification method is based on the recursive linear least square algorithm. The inverse method is based on the constant function specification approach. Results obtained during machining lead to predict the tool wear and possible tool positioning defect.

“…Experimental data on the temperature distribution have been obtained by different means. Use of thermocouples and extrapolation of the results based on the solution of the heat equation in the tool provide an estimate of the temperature field and in particular of the mean contact temperature, Groover and Kane (1971). Other procedures are based on infrared technique measurements Boothroyd (1963), or on the analysis of the structural modifications in the tool material, Wright and Trent (1973).…”

reporting original research on the mechanics of solids. Emphasis is placed on the development of fundamental concepts of mechanics and novel applications of these concepts based on theoretical, experimental or computational approaches, drawing upon the various branches of engineering science and the allied areas within applied mathematics, materials science, structural engineering, applied physics and geophysics. The main purpose of the Journal is to foster scientific understanding of the processes of deformation and mechanical failure of all solid materials, both technological and natural, and the connections between these processes and their underlying physical mechanisms. In this sense, the content of the Journal should reflect the current state of the discipline in analysis, experimental observation and numerical simulation. In the interest of achieving this goal, authors are encouraged to consider the significance of their contributions for the field of mechanics and the implications of their results, in addition to describing the details of their work.© 1998 Elsevier Science Ltd.
