    • Optimisation of the design of the basic elements of the bearing system of a heavy CNC machining centre 

      Gorbunov, Victor Petrovich; Trofimchuk, Artem Sergeevich (BrSTU, 2021)
      By the example of a three-dimensional model of the bearing system of a heavy multipurpose CNC machine, the influence on the deformation displacements of the structural design of the basic elements, the location of the supports is considered, which made it possible to identify weak points in the structure ...
