In this paper, the rock breaking process of the cutting teeth is analyzed, firstly, based on the rock constitutive model and damage law, the simulation model is established by finite element software, and the cutting load of the cutting teeth in the plane rock, rock ridge and rock ridge root is analyzed, and on this basis, the load of the rock and the cutting tooth during scraping is analyzed through the cloud map. The effects of camber angle, depth and cutting speed on cutting force and crushing ratio were analyzed.
