摘要：
This paper proposes a model of the burr formation mechanism when burrs are formed in the feed direction during turning operation. Two cases have been considered in this study: continuous burr development, when the burr grows uninterruptedly; and discontinuous development, when the burr being formed is cut off and is renewed with each revolution of the workpiece. The model allows predicting burr height and thickness, and is able to simulate burr development. Experimental verification of the model was carried out during turning of aluminum alloy A16061-T6. It was confirmed through the experiment that burr thickness can be predicted with considerable accuracy and that burr height can be determined with a maximum error of about 30%. The experiment also proved that the model is suitable for the description of burr development in both continuous and discontinuous cases of burr formation. (c) 2006 Elsevier Ltd. All rights reserved.
