title = "Comparison of dimensional repeatability of deformation machined components with sheet metal components",
abstract = "This paper presents the results of repeatability studies of Deformation Machined components. Deformation Machining (DM) is a hybrid process which combines two emerging manufacturing processes, machining of thin structures and single point incremental forming (SPIF). This hybrid process enables the creation of structures that have geometries that would be difficult (sometimes impossible) to create using any other processes. Studies are performed to experimentally determine the dimensional repeatability for part features created by the DM process 'bending mode', in which a thin vertical wall is machined on the part, and then incrementally bent with a single point forming tool. The repeatability of DM components is compared with sheet metal components made by single point incremental forming and conventional bending. The results of this study indicate that the DM process is not capable of holding tolerances as tight as a standard milling process. This may be due to local variations in material properties that influence the yield strength and resulting springback. However, thin components created by DM are more repeatable than similar components created from sheet metal using SPIF, but less repeatable than components created by conventional bending of sheet metal.",
