U ovom radu opisana je problematika konstruiranja složenog kalupa, pomoću programskog alata SolidWorks. Za konstruiranje kalupa korišteni su programski moduli Surface i Mold, pomoću kojih se izradio zahtjevni 3D model žlice (programski modul Surface), te s obzirom na nju konstruirani su matrica i žig (programski modul Mold). Nakon 3D modeliranja kalupa, izrađena je simulacija 3D obrade glodanja u programskom modulu SolidCAM, gdje je nakon definiranja obrade generiran G-kod za stroj Haas VF-6 na kojemu je sam kalup i izrađen.In this thesis we work on modelling a complex mold, with the help of SolidWorks software. For constructing this mold, moduls of Surface and Mold were used for making the spoon (Surface) and then, based on the spoon, mark and countermark (Mold) where made. After modelling a mold in 3D, 3D milling simulation was made in the SolidCAM module, where a G-code of milling for the Haas VF-6 was generated and a mold was made
