“…The layer laminated manufacturing (LLM) is referred to as a hybrid manufacturing process as it combines additive joining of coherent layers with their subtractive structuring before or after joining. Numerous process variants in terms of the layer materials and the joining process have been subject to research within the last decades [16][17][18][19][20]. LLM has received limited industrial attention so far, even though it allows unique design freedoms such as enclosed inner cavities and virtually any material combination.…”

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.

This study presents an approach for calculating the stress and deformation increase in the modulation of magnetically geared machines using a mathematical method. An analytical method is employed to obtain the magnetic force density acting on the modulation components. Afterward, the proposed mathematical method predicts the mechanical characteristics. The 9 slots/32 poles/19 modulations model was evaluated via a comparison with the finite element method simulation.

“…Besides the introduction of a stiff and strong material for the segment ring cage, the radial thickness of the segments is increased with 33% from 3 to 4 mm. In [58] the stiffness of the segment ring is improved by inserting nonmagnetic support rings into the segment ring stack. Where the segments are only connected by a thin bridge (0.6 mm thick for MagCon V2), these support rings have the full height of the segments which improves the stiffness.…”
