Internal grinding of thermoprotective rubber coatings

Resumo

The internal abrasive machining of thermoprotective rubber coatings with constant retaining force on the grinding wheel is studied, theoretically and experimentally. A model of rubber failure in abrasive machining is proposed on the basis of the work of a single abrasive grain in contact with the machined surface. A relation is established between the components of the grinding force and the normal and tangential contact stresses at the working surfaces of a single grain of the wheel.
