Abstract

Most research on the representation of swept volumes has been limited to motion of rigid objects. In this study, a Sweep Differential Equation (SDE) approach is presented for the representation of deformed swept volumes associated with flexible objects. The deformed swept volume analysis is integrated with machining mechanics to account for cutter deflection in NC simulation. End milling is modeled and analyzed and the cutter deflections are computed and integrated with an SDE based software program which is developed in C++ for the generation of deformed swept volumes. It is shown that this approach constitutes an effective NC simulation technique with capabilities for geometric verification and machining tolerance checking.
