Abstract
In machining operations, a burr is an undesirable material formed by plastic deformation in a workpiece. With the ongoing industrial developments, it has become an important issue to efficiently remove burrs. Several deburring methods have been developed to remove specific burrs that require special machining. However, to remove burrs formed while machining at the CNC machining center, deburring tools must be developed. In a previous study, a new deburring tool was developed by the authors. In this study, the influence of the rake angle and stiffness of the new deburring tool was analyzed to improve performance. The theoretical model was driven considering the rake angle and stiffness, and experiments were carried out to validate the model. Especially, conditions based on the designed rake angle and stiffness to effectively remove burrs, which is difficult, at the exit surface were suggested.
