Abstract
Kod strojne obrade postoje različiti načini mehaničkog i nemehičkog stezanja materijala koji se obrađuje. Vakuumski stol jedan je od nemehaničkih načina stezanja prilikom strojne obrade pločastih materijala. Generiranje vakuuma ostvaruje se pomoću vakuumskih pumpi ili generatora vakuuma (vakuumskog ejektora). Vakuumskim proračunom, za slučaj promjene iznosa površine stezanja uz konstantni iznos vakuuma te za slučaj promjene iznosa vakuuma (promjenom iznosa ulaznog pogonskog tlaka u vakuum ejektoru) uz konstantni iznos površine stezanja, definiraju se moguće sile stezanja te režimi obrade na vakuumskom stolu. Dizajn vakuumskog stola izveden je pomoću 3D CAD programskog okruženja Autodesk Inventor, dok je priprema za strojnu obradu izvedena pomoću CAM programskog okruženja Fusion 360 s pripadajućim postprocesorskim paketom za CNC glodalicu na kojoj je obavljena sama strojna obrada vakuumskog stola.
Abstract (english)
In machining, there are different methods of mechanical and non-mechanical clamping of the material being processed. The vacuum table is one of the non-mechanical methods of clamping during the machining of plate-like materials. Vacuum generation is achieved using vacuum pumps or vacuum generator (vacuum ejector). With vacuum calculation possible clamping forces and processing regimes on the vacuum table are defined for the case of changing the value of clamping surface with a constant amount of vacuum and for the case of changing the amount of vacuum (by changing the value of input driving pressure in the vacuum ejector) with a constant value of clamping surface. The design of the vacuum table was made using the 3D CAD program Autodesk Inventor, while the preparation for machining was made using the CAM program Fusion 360 with the corresponding post-processing package for the CNC milling machine on which the machining of the vacuum table itself was done.
