### Study on the friction coefficient in grinding

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 ...
