Abstract
Abstract Several research works have been done to assess the effect of the cutting depth on the cutting forces when using picks. In this case, the cutting tests need im-portant equipment to cut rocks, to register the cutting force and to determine the cutting force value. The purpose of this research work is to simulate the laboratory rock cutting tests to determine the cutting force, using commercial software; and to compare the cutting force values to those obtained in the la-boratory. In the simulation, we took a gypsum rock sample as the specimen,. We simulated the separation of the rock chips from the specimen and the sub-sequent breakage into multiple fragments. In the simulations, a cutting pick was compared with a stationary rock sample. The simulations were conducted at a same constant velocity for different cutting depths. The simulations showed that the depth of cut has a significant effect on the cutting force, and the values of the cutting force in the simulation are very close to those obtained in the laboratory.
Highlights
Research on the mechanical excavation of rocks has been undergoing since the 50s when a large interest was given to the rock cutting process to improve the production at low cost
From that time until now, several research works either theoretical, practical or numerical have been carried out, where a number of theories were developed to estimate the intensity of the cutting force and other cutting parameters in the excavation of rocks by machines
The NCB research results showed that the cutting force is lower as the wed-ges of the picks are narrow
