文摘

A new cutting theory is proposed to explain rock's cutting and chipping mechanisms Experimental data is presented in support of force and chip formation predictions. The predictions of force responses and rock failure behaviors agree with the tests. The theory provides insights into the optimization of rock cutting processes.
