Abstract:With additive manufacturing technology, the production of difficult and costly parts, which are difficult to manufacture with traditional production methods in the industry, has become easier, and production of complex or integrated or porous parts has become possible. The parts, which are in a multi-part structure, can be produced as one piece as a whole, offers advantages in various applications. In this thesis, revolute joint design approaches are proposed for the parts that will be designed as integrated with additive manufacturing. Developed design approaches have been applied in electron beam melting method which is one of the additive manufacturing methods and design rules for additive manufacturing have been introduced. In this context, in order to see the integrated production capabilities of the EBM device and to determine the overall dimensional margin of error of the system, a test piece including integrated structures was produced and measurements of this test piece were performed. In this study, the applicability of the tolerances required to produce an industrial product in accordance with the working conditions on the integrated revolute joints was also studied. Five different integrated revolute hinges were designed for the application. ISO Fit table is used for tolerances. The tolerance ranges were determined to be greater than or equal to the overall dimensional error of the system obtained from the measurement results of the test piece. After the production of the revolute joints with 5 different designs of 18 mm diameter, the bearing gaps were measured with the experimental setup established and compared with the pre-production tolerances. Thanks to different design approaches according to the measurement results, the lowest clearance value obtained in the integrated revolute joints was measured as 10 μm.
