Temperature investigation of coated workpieces in intermittent grinding with a cup wheel

The effective width of the moving heat source is presented and the shape of the grinding block is simplified in order to use the traditional heat source model in modelling flat grinding with a cup wheel. Both triangular and rectangular heat source models are presented and compared with experimental results. The heat transfer process, the end-face temperature of a single wear particle, and the one-dimensional heat transfer model are integrated to study the heat flux into the workpiece. The energy partition ratio is obtained under conditions of different grinding parameters in order to make the temperature model precise. The feasibility of the temperature model is validated by experimental results, and the influence of grinding parameters on the grinding temperature is also analysed.
