Lavine, Adrienne S.
An exact solution for surface temperature in down grinding. (English)
[J] Int. J. Heat Mass Transfer 43, No.24, 4447-4456 (2000). ISSN 0017-9310

Summary: A model has previously been developed [{\it T.-C. Jen} and {\it A. S. Lavine}, J. Heat Transfer 117, 473-478 (1995)] for heat transfer in down grinding. A numerical solution algorithm was used to solve the system of equations. In this paper, an exact solution is found for this set of equations. The effect of location of heat generation (i.e., at wear flats or shear planes) is explored for three typical grinding conditions: conventional grinding with aluminum oxide abrasives, creep feed grinding with aluminum oxide abrasives, and conventional grinding with cubic boron nitride (CBN) abrasives. It is found that during grinding with CBN, there is a strong effect of the assumed location of heat generation.
