Abstract: 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%.

Abstract: The paper represents an experimental study of the burr formation mechanism in feed direction. The influence of tool angles and workpiece angles, as well as and other cutting conditions on burr dimensions is considered. The work contains experimental graphs of burr cross-sections obtained using a laser measurement system at various stages of burr formation. The analysis of the experimental work shows that, depending on the cutting conditions, a few mechanisms of burr formation can be distinguished. The study could be useful in the search for optimal tool geometry for burr minimization and for the modeling of a burr formation mechanism.
