Simulation of Burr Formation in Feed Direction in Turning

The paper proposes a model of burr formation in feed direction during turning operation. Two cases have been considered in the model: continuous and discontinuous burr development. A computer program, made on the base of the model, allows simulation of burr development, and predicting burr form and dimensions. Experimental verification of the program showed that the model is suitable for the simulation of burr development in both continuous and discontinuous cases of burr formation. The experiment also proved that burr thickness can be predicted with considerable accuracy and that burr height can be determined with a maximum error of about 30%.
