## Conclusions

1. 1.

A description is given, with the aid of a mathematical model, of the effect of porosity upon the temperature generated in work during grinding.

2. 2.

Data are presented enabling the extent to which porosity changes the temperature in the surface layer of a sintered part to be assessed with adequate accuracy for practical purposes.

3. 3.

The results of the theoretical and experimental investigations have revealed certain features in the thermophysics of machining of porous materials that have a bearing on the development of surface finish in the grinding of sintered parts.
