A numerical method is applied to analyze the heat-conduction problem in a g
rinding process. At the beginning, the time and space domains of the proble
m are discretized based on the finite difference method and then a linear i
nverse model, in which the solution procedure requires no iteration, is con
structed to identify the temperature distribution and the heat flux along t
he cutting path. The excess heat generated in the grinding process may caus
e thermal damage to the workpieces and the wheels, however, direct measurem
ent is extremely difficult or simply impossible in the contact zone of the
grinding process. The inverse approach provides an alternative. According t
o this study, a few data measured wherever the temperature measurement can
be done are sufficient to determine the temperature and the heat flux on th
e workpiece surface. (C) 2000 Elsevier Science S.A. All rights reserved.
