Abstract
The friction between the abrasive grains and workpiece is a crutial factor determining the main grinding output. Few studies have been carried out investigating the values of the friction coefficient in grinding, due to the difficulty of direct measurement. In this paper, a mathematical model of the friction coefficient in grinding has been established with the aid of a new grinding parameter C ge. Heavy grinding with different wheels and also single-grit grinding tests have been conducted for various work materials. The friction coefficients under different grinding conditions have been obtained using the model and the experimental results. The effects of grinding speed, wheel and work material on the friction coefficient have been discussed.
