Abstract
U ovom radu ukratko su prikazani povijesni razvoj CNC alatnih strojeva, osnove obrade odvajanjem čestica odnosno glodanje, prednosti komercijalnih CNC alatnih strojeva u odnosu na konvencijalne alatne strojeve te osnovna mehanička struktura potrebna za uspješno projektiranje takvoga stroja. Prezentirana je izvedba troosne portalne CNC glodalice velikih dimenzija predviđene za izrezivanje formi iz pločastog materijala. Pokrivena su sva područja kod konstruiranja jednog ovakvog stroja. Prikazani su postupci odabira potrebnih mehaničkih komponenti kao i sam postupak konstruiranja kompletnog stroja. Stroj je u radu podijeljen na 3 glavna podsklopa (X, Y i Z os) koji su zasebno, ovisno jedni o drugima, proračunati i konstruirani. Izrađeni su CAD modeli i potrebna dokumentacija. U sklopu rada izvršen je proračun najopterećenijeg dijela stroja metodom konačnih elemenata, a provedena je i analiza u dostupnom računalnom programu. Na temelju dobivenih proračunskih i računalnih rezultata provjerena je točnost postupaka i rezultata. Za proračun mehaničkih komponenti i konstrukcije portalne CNC glodalice, izradu skica te izradu CAD modela i tehničke dokumentacije korišteni su programi SolidWorks, MatLab, CorelDrav, AutoCAD.
Abstract (english)
This paper presents a brief overview of the historical development of CNC machine tools, the basis of milling, the advanteges of commercial CNC machine tools compared to conventional machine tools and the basic mechanical structure required for successful design of such machine. Designing procedure of a three-axis portal CNC milling machine of large dimensions for sheer metal cutting is presented. All areas are covered for designing such a machine. The procedures for selecting the required mechanical components as well as the procedure for the complete machine design are shown. The machine is divided into 3 main sub-groups (X, Y and Z axis), which are, depending on each other, calculated and designed. CAD mmodels and required tehnical documantation have been developed. As part of the work, the analysis of the most loaded part of the machine was performed by the finite element method and an analysis was made in the available computer program. Based on the results, the accuracy of the procedures and the results were verified. SolidWorks, MatLab, CorelDraw and AutoCAD softwares were used for calculating the mechanical components and design of the portal CNC milling machine, drafting, CAD modeling and technical documentation.
