TOPOLOGY OPTIMIZATION OF HORIZONTAL CROSSBEAM OF PORTAL MILLING MACHINE

Popis výsledku v původním jazyce

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 material reduction lead to stiffness descent, problems with harmonic frequencies or technological obstruction. Precise material distribution reduce weight and conserve the stiffness of crossbeams. Through this approach the best structure of loaded part is identified with respect to combination of weight and low compliance. On one hand, optimization identifies the best solution for required, specific boundary condition, but on the other hand it causes lower performance in other unspecified circumstances of loading. Due to that, a precise definition of boundary condition was crucial. Horizontal crossbeam of portal milling center was optimized. Part was optimized isolated from overall assembly. Boundary conditions which define connection between crossbeam and columns was defined with respect to real connection. Hydrostatic guidance between column and crossbeam provides specific connection. It requires precise definition because of the crucial influence on calculation. At the same time, minimal deformation of hydrostatic surfaces is required. Complex topology optimization leads to better material utilization, cost-effective production and higher performance of machining.
