Topology optimization of horizontal crossbeam of portal milling machine

Displacements caused by cutting forces, gravity or mass inertia influent the overall precision and productivity of milling machines. Economic pressure leads to cost reduction of milling centers. Reduction of weights should decrease prime-material costs of milling center. However, non-conception materi...
