	abstract = {Requirements on burr height and burr amount on machined parts are getting stricter. This leads to method development from manufacturing companies to predict burr distribution and its size along part edges. A deeper understanding of burr formation mechanisms will assist to more accurate model development. This study aims to analyze the exit burr formation, which is formed during orthogonal cutting of a brittle cast aluminum alloy. A customized Digital Image Correlation (DIC) system with the help of a high-speed camera was used to measure the displacements fields. It calculates strain fields during burr initiation and development in orthogonal cutting of T7 heat-treated cast Aluminum alloy ENAC-AlSi7Mg0.3 as well. Those results are then qualitatively compared with a numerical model of the burr with chamfer formation developed and simulated using a Finite Element Method (FEM), to ensure a good correspondence between experiments and simulation. This model is used to complete the DIC study of burr with chamfer formation mechanisms during crack propagation leading to chamfer formation. The analysis of numerically obtained stress triaxiality fields and of DIC observations from experiments are compared to the assumptions made from analytical models. Finally, necessary improvements of an existing burr formation analytical model are proposed.},

	abstract = {Burr formation during parts manufacturing is a significant problem that companies try to minimise or eliminate. The present work aims to study the burr formation mechanisms in a cast aluminium alloy. Orthogonal cutting tests are performed using different uncut chip thicknesses and tool rake angles. To analyse burr formation mechanisms, the work material state of stress and triaxiality distribution in the chip root was investigated via numerical simulations. Results show that the uncut chip thickness has an effect on burr morphology and burr cumulation while tool rake angle influences burr height on high uncut chip thicknesses.},
