Abstract：Based on the disc cutter slitting wear experiments and ARCHARD wear model, a disc cutter slitting wear simulation model is built using DEFORM-2D, and simulated profile of worn disc cutter are in good agreement with the experimental profile. It is found that the wear rate of each point of the disc edge is different. In a slitting cycle, from boundary point of cylinder surface to boundary point of side surface of disc edge, the wear depth firstly increases gradually and then decreases rapidly, and the disc edge changes from initial circular arc to worn elliptical arc. The 3D cloud image of the disc cutter wear during the steady wear stage is calculated and appears as a hill inclined to the side surface of disc cutter. The relationship between the sharpness of disc edge and wear distribution is analyzed. The sharper the disc edge, the harder the wear rate. As the sharpness of disc edge decreases, wear peaks and non-uniformity decrease.
