  @article{Helfesrieder.2021b, abstract = {Load-oriented lightweight structures are commonly designed based on topology optimization. For machine tool parts, they enable the reduction of moving masses and therefore increase the resource and energy efficiency of production systems. However, this usually results in complex part structures that are difficult or impossible to produce using conventional manufacturing methods. In this paper, a hybrid layer laminated manufacturing (LLM) method is proposed enabling manufacturing of topology-optimized machine tool parts. The method is referred to as hybrid, as the subtractive structuring of metal sheets is combined with the additive joining of the sheets by adhesive bonding. This enables enclosed inner cavities without support structures, which are used to approximate the optimal density distribution from a topology optimization via manufacturing. The proposed LLM method is validated on the basis of a bearing block of a ball screw feed drive. A experimental study in the time and frequency domain on a test rig confirms the principle suitability of the LLM method for the production of industrial applicable lightweight components.}, author = {Helfesrieder, Nico and Neubauer, Michael and Lechler, Armin and Verl, Alexander}, doi = {10.1007/s11740-021-01095-7}, file = {Helfesrieder, Neubauer et al. 2021 - Hybrid manufacturing of topology optimized:Attachments/Helfesrieder, Neubauer et al. 2021 - Hybrid manufacturing of topology optimized.pdf:application/pdf}, issn = {0944-6524}, journal = { Production Engineering Research and Development}, month = {12}, title = {Hybrid manufacturing of topology optimized machine tool parts through a layer laminated manufacturing method: Practical validation using the example of a bearing block}, url = {https://doi.org/10.1007/s11740-021-01095-7}, year = 2021 }

  @article{Helfesrieder.2020, abstract = {The great flexibility provided by generative manufacturing offers immense potential for the structural component optimization. However, this freedom needs to be utilized by appropriate CAx tools. In this paper, we present a novel slicing method, enabling the automatic generation of topology-optimized Laminated Layer Manufacturing (LLM) parts. With this method a part of arbitrary shape can be automatically sliced and equipped with a uniform virtual grid that is suitable for manufacturing. The optimal density distribution is then mapped onto the individual slices and locally approximated through the introduction of variably shaped cavities. By using 3D modeling techniques all LLM sheets are modeled parametrically and assembled automatically. To verify the functionality of the presented method, it is applied to two practical parts and compared with a conventional topology optimization method.}, author = {Helfesrieder, Nico and Lechler, Armin and Verl, Alexander}, doi = {10.1016/j.procir.2020.04.048}, issn = {22128271}, journal = {Procedia CIRP}, pages = {38--43}, title = {Method for generating manufacturable, topology-optimized parts for Laminated Layer Manufacturing}, url = {http://www.sciencedirect.com/science/article/pii/S2212827120306144}, volume = 93, year = 2020 }
