【Abstract】 On the basis of the results of the rock cutting mechanism research, the characteristics of rock cutting forces of diabase, granite and marble are analyzed in detail, using the single factor method and quadratic combined orthogonal regression design method. The principles of selection of the cutting technological parameters are proposed. The empirical formulas of rock cutting forces are given. They can be referred to the design of the rock cutting machinery. The results obtained have provided a foundation for the further study of the theoretical formulas of rock cutting forces.更多还原
