Abstract
The prediction of grinding force has great significance in improving grinding quality and efficiency. This paper presents a predictive force model in plunge facing grinding considering both the cutting mechanism of single grain and the random nature of wheel topography. The model includes cutting deformation force and frictional force, which mainly depend on undeformed chip cross-section area and wear flat area of grains. In order to overcome the difficulties for calculating the cross-section area of irregular polyhedral grains, a digital graphic scanning (DGS) method is proposed in this research. Single grain scratch test and hardness test are carried out to obtain the model coefficients. The validation experiments performed on a face grinding machine show a good match of the predictive and measured forces for different grinding parameters.
