Abstract
Obradni centri predstavljaju osnovne jedinke (module) pri gradnji fleksibilnih obradnih sustava. Prigon glavnog gibanja obradnog centra treba udovoljiti visokim zahtjevima točnosti obradbe i krutosti zbog čestih promjena opterećenja i učestalosti vrtnje kod korištenja različitih vrsta reznih alata. Cilj je rada proračunati jedan takav prigon glavnog rotacijskog gibanja vertikalnog glodaćeg obradnog centra. Nakon uvoda, u drugom poglavlju rada dan je prikaz obradnih centara, njihova podjela,osnovne značajke te neke od mogućih izvedbi. U trećem poglavlju prikazane su najčešće izvedbe glavnih prigona numerički upravljanih alatnih strojeva. Četvrto poglavlje daje smjernice projektiranja glavnog vretena i ostalih pripadajućih dijelova glavnog prigona alatnog stroja. Središnji dio rada, peto poglavlje, čini proračun, od izbora ulaznih parametara i izbora alata te režima obrade, preko izbora pogonskog elektromotora, proračuna remenskog prijenosa, dimenzioniranja glavnog vretena i izbora leţajeva do kontrole glavnog vretena, izbora drţača alata i sustava stezanja alata. U šestom poglavlju nalazi se dijagram toka proračuna prigona glavnog gibanja, a nakon toga zaključak rada.
Abstract (english)
CNC machining centres represent the primary individuals in the construction of flexible machining systems. Machining centres main driving mechanism must meet the high requirements for the processing accuracy and rigidity due to frequent load and speed changes upon using various types of cutting tools. The aim of this thesis is to calculate one such driving mechanism of the main rotational motion of a vertical milling machining centre. After the introduction, in the second chapter, CNC achining centres, their classification, main features and some possible implementations are presented. The third chapter discusses the most common designs of numerical controlled machining centres main driving mechanisms. The fourth chapter contains guidelines for the design of the main spindle and other associated parts of the machines main driving mechanism. The central part of this thesis, the fifth chapter, is the calculation, from input parameters, tool selection and processing modes, through drive motor selection, belt drive calculation, main spindle dimensioning, main spindle bearings definition to main spindle control, tool holder and tool clamping system selection. The sixth chapter contains a calculation flow diagram of the main driving mechanism. Thereafter is the conclusion.
