Abstract—Rock cutting is modeled using discrete element modeling in which the cutter is defined by solid walls, while a rock sample is approximated as a packing of bonded spherical particles following certain interaction laws. This paper presents analysis of the numerical effects on the cutting force destroying the rock that are due to the elements size and configuration of the model. The content includes the computation results along with recommendations on selection of the numerical model parameters of a sample to obtain required accuracy of modeling.
