Abstract: The impact fracture of cemented carbide inserts is very severe during heavy-duty cutting. In this paper, the occurrence condition of insert impact fracture was first conducted by simulating the heavy-duty cutting, with the maximum principal cutting force determined as 32 KN and the cutting temperature as 1,000°C. Subsequently, an insert impact fracture limit model was established based on impact load and cutting mechanics. To study the variation regularity of its mechanical property with temperature, a high-temperature tensile test of cemented carbide was carried out. In conclusion, based on simulation, fracture limit model, and experimental results, the impact fracture analysis contour was plotted using Matlab software. The research findings can provide the basis for optimisation of heavy-duty cutting parameters as well as reducing the impact fracture of inserts.
