Popis:	□ Determination of the partition ratio is fundamental to a thermo-mechanical approach to the grinding process. To establish the energy balance, accurate measurements and numerical modelling must be combined. In this work, such a method is applied to the grinding of a HVOF WC-Cr-Co hard coating. A double pole grindable thermocouple was developed to measure the temperature in the arc of cut, and its effective length. The heat flux absorbed by the workpiece is found by fitting the numerical solution to the temperature profile measured during the cooling phase, behind the contact. Identical results for the heat flux may be obtained by fitting the results to the analytical solution from moving heat source theory, but the maximum interface temperature is underestimated. A finite element solution, using MSC Marc software allows a closer approach to the maximum temperature measured at the interface during grinding, provided that the thickness of the coating is correctly modelled.
