Abstract
We study the surface temperature expression in flat dry grinding for a general heat flux profile entering into a workpiece within the friction strip due to contact between wheel and workpiece. This expression involves a non-tabulated integral that we proceed to calculate. Since the maximum temperature is reached at the workpiece surface in the stationary regime, the advantage of this calculation is that the maximum temperature can be computed very rapidly, so it can be applied in on-line monitoring of the grinding process in order to avoid thermal damage.
Additional Information:
This paper is focused onto the calculation of the following function, defined as
where K0 (x) denotes the MacDonald’s function of zeroth order. This integral appears when you want to calculate the surface temperature of a workpiece in flat dry grinding, considering an arbitrary heat flux profile entering into it.
