Burr research is undeniably highly complex. In order to advance understanding of the process involved several techniques are being implemented. First a detailed and thorough examination of the burr forming process is undertaken. The technique is difficult, intricate and time consuming, but delivers a large amount of vital physical data. This information is then used in the construction of empirical models and, in some case lead to development of FEM models. Finally using the model as a template, related burr formation problems that have not been physically examined can be simulated and the results used to control process planning resulting in the reduction of burr formation. We highlight this process by discussing current areas of research being followed at the University of California in collaboration with Boeing and the Consortium on Deburring and Edge Finishing (CODEF).
