Abstract

Based on burr fracture morphology and burr geometry, it is concluded that the main cause of burr formation is the overall metal slip caused by the feed force of sawing and shearing. Based on the assumption that the feed force is uniformly distributed along the incision plane, the burr thickness calculation model for sawing and shearing is formed by coupling the sawing and shear force model and the blanking force model. For preheating temperatures of 500\(\thicksim \)900∘C, feeding speeds of 30\(\thicksim \)90 mm/s, and saw tangent speeds of 3000\(\thicksim \)9000 mm/s, 30 mm × 30 mm GCr15 square steel was used for experiments. Through the calculation model given in this paper, the rule for the influence of the process parameters on burr thickness was obtained. Finally, a sawing and shearing experiment was carried out, and the results show that the maximum relative error between the experimental data and the calculated results is 15%, which verifies the reliability of the calculation model.
