Temperature distribution in workpiece during scratching and grinding
The heat transfer problem of a moving heat source along the surface of a half space was studied analytically and numerically. For the 2D problem, the heat source was a strip moving source and for the 3D problem, the heat source was a square moving source. Analytical solutions are available only for adiabatic conditions as given by Carslaw and Jaeger [H.S. Carslaw, J.C. Jaeger, Conduction of Hea...
متن کاملHomochirality beyond grinding: deracemizing chiral crystals by temperature gradient under boiling.
A single-chirality solid phase can be obtained in boiling solutions containing a racemic mixture of left- and right-handed enantiomorphous crystals due to dissolution-crystallization cycles induced by a temperature gradient. This phenomenon provides further insights into asymmetric amplification mechanisms under presumably prebiotic conditions.
متن کاملGrinding Temperature Measurements in MgO-PSZ Using Infrared Spectrometry
Introduction When the grinding wheel specifications are properly chosen, a SiC grinding wheel performs remarkably well for grinding partially stabilized MgO-ZrO2 ceramics (MgO-PSZ). Rather surprisingly, the highest Gratios are obtained at higher grinding rates for the SiC wheel. This, and the fact that SiC grinding wheels can be readily shaped for use in precision cylindrical form grinding, has...
متن کامل[Thermographic study of temperature gradient during ear surgery intervention].
BACKGROUND During middle ear surgery manipulations like burring, cooling with water, suction or even screwing cause changes of temperature which should be known to the surgeon. METHOD An infrared thermovision device was introduced for registration. RESULTS Thermography is an easy way for continuously recording thermic effects during surgery. If sufficient cooling is guaranteed, no temperatu...
متن کاملTHE EFFECT OF GRINDING TIME ON THE SPECIFIC SURFACE AREA DURING INTENSIVE GRINDING OF MINERAL POWDERS
Abstract: the changes of BET surface area of a mineral substance during intensive grinding process. Validity of the proposedmodel was tested by the experiments performed using a natural chalcopyrite mineral as well as the published data. Itwas shown that the model can predict the experimental results with a very good accuracy and can be used to predictwhat may happen under the similar experimen...
