Abstract

The temperature of a cutting grain when cutting has been completed is investigated experimentally and theoretically. As the model of the cutting grain, a conical tool of ceramic is used. The temperature of the grain at various times after cutting is measured using an infrared radiation pyrometer with an optical fiber. The cooling process of the cutting grain during air cutting is analyzed by reference to unsteady-state heat transfer theory. The cooling of the grain is extremely rapid, that is, the temperature of the grain decreases to one fourth of the maximum temperature in 1 ms after cutting. The maximum temperature of the cutting grain reached at the end of cutting is estimated to be the melting point of the work material.

Cutting temperature and energy partitioning in grinding
2021, Tribology and Fundamentals of Abrasive Machining Processes: Third Edition
The temperatures generated by abrasive machining processes are generally much higher than in other cutting processes like turning and milling. Hence, optimal and well-designed abrasive machining processes should be employed to guarantee the surface quality of finished parts and achieve damage-free surfaces and subsurfaces, desired surface roughnesses, and compressive or neutral residual stresses. Lapping, polishing, honing, and low-stress grinding enhance and improve the fatigue life of produced parts. The temperature generated via abrasive machining can lead to surface and subsurface damage, such as diffusion, softening, phase transformation, thermal expansion, and chemical reactions and oxidation, that negatively affect the performance of finished parts. This chapter considers heat generation and partitioning and further explores relationships between the process energy, selected grinding conditions, and aspects of process design to predict process temperatures and realize high process productivity or desired surface integrity.
On The Measurement of Temperature in Material Removal Processes
2007, CIRP Annals - Manufacturing Technology
Because it is key to understanding the performance of material removal processes and resultant workpiece quality, the measurement of temperature during material removal is done extensively. We review several widely used temperature measurement methods and show how they can be applied to temperature monitoring during material removal. Since there is little documentation on measurement uncertainties as relates to material removal, this paper outlines the physics of each method, detailing the sources and evaluation of uncertainty. Finally, using criteria critical in measuring material removal, methods are compared, and the results presented in guide-format for participants in this field of work.

Temperature of work materials irradiated with CO<inf>2</inf> laser
1997, CIRP Annals - Manufacturing Technology
Temperature of a workpiece irradiated with CO₂ pulse laser, which is one of the most important factors for deciding the suitable conditions in the cleavage cutting of brittle materials and the forming of sheet metals, is investigated experimentally and theoretically. The surface temperature is measured by a new type of Infrared Radiation Pyrometer using a fused fiber coupler. This pyrometer makes it possible to measure the flush temperature of a very small object without emissivity influencing the results. The temperature distribution in the surface layer of the workpiece is calculated numerically using FEM. The energy absorptivity of the workpiece is obtained by comparing the experimental results with the calculated ones.
