Grinding force performance with different types of grinding fluids based on a semi-empirical force model

摘要

In the present paper, a semi-empirical grinding force model is developed combined with the achievements of previous researchers by composing effects of normal and tangential grinding forces in two main parts respectively: cutting force and sliding force. This model is used to predict the total normal and tangential force in the surface grinding. These force components were expressed in terms of the grinding process parameters such as wheel speed, workpiece feed rate, width of the workpiece and depth of cut. There are four unknown coefficients in each equation which can be determined by experiment results at specific conditions with the variations of grinding process parameters. Four different water-based grinding fluids were tested for different specific grinding conditions. The calculated normal and tangential grinding results are compared with the experimental ones. To have a better agreement with experiment data, shallow grinding condition is chosen to obtain the modified model.
