There are numerous advantages to rigidly holding a workpiece: feed rates can be increased and cutting times reduced, cutters last longer and impart finer surface finishes, and more-accurate parts are produced. At trade shows where vendors offer demonstrations, you rarely see flimsy, difficult-to-hold parts being machined. In the real world, however, such parts are common. Holding parts for secondary operations, such as drilling holes on an edge, can also be challenging.
