Abstract

The influence of an exit surface angle on drilling burr formation was analyzed. The experimental research found that a burr forms on only a certain portion of a hole when an exit surface is not perpendicular to a drill path. An effective interaction angle was newly defined and the concept of degree of plastic deformation was introduced in order to explain this phenomenon. The burr forming location predicted from the effective interaction angle was verified with experimental results.
