Many additive parts need machining in order to be functional. It may be that machining is required to meet dimensional tolerances or to meet surface finish requirements for mating or sealing surfaces, for example. It may be that the part contains features that are difficult to print such as threaded holes or holes with high aspect ratios. These parts may be made in hybrid machine tools (additive and subtractive in the same workspace) or they may be made by hybrid processes (separate additive and subtractive machines). In such cases, the total part cost including the additive and subtractive operations can be reduced if the additive preform is designed with the subtractive operations in mind. The additive preform can contain features to help locate the part and features to help fixture the part in the machine tool. Stiffening features can be used so that the part is stiff enough to support the machining forces that will be required. This presentation will show both the general concepts, and specific examples of additive for subtractive.
