Numerical Investigation of the Rock Cutting Performance of a Circular Sawblade

Abstract

The rock cutting process with a circular sawblade and the rock breaking mechanism of rock are studied with a numerical simulation method in this paper. The influence of cutting parameters of the circular sawblade on cutting force, rock damage, and specific cutting energy in the process of circular sawblade cutting rock is researched. The cutting force increases with the feed speed and an increase in cutting depth and decline in rotation speed. Cutting rock with double circular sawblades can reduce cutting force. However, the specific cutting energy declines with the increase in cutting depth and the decline in the distance between the double circular sawblades. Cutting parameters have a great influence on the damage range of rock. The research results can be applied to rock processing with a circular sawblade.

A Numerical Model for Rock Cutting with Diamond Circular Saw Blade Based on Smoothed Particle Galerkin Method

“…CAE techniques provide a powerful means of explaining the damage, fracture, and fracture behavior of the brittle and hard rock under high-speed impact and penetration. With the fast development of CAE technology [2], many three-dimensional numerical models have been developed for the study of the rock cutting process [3].…”
