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 modeling an complex mold, with a help of software SolidWorks. For constructing this mold, moduls of Surface and Mold were used, for making of spoon (Surface), and then based on spoon it was made mark and countermark (Mold). After 3D modeling of a mold, it was made 3D milling simulation in modul of SolidCAM, where was generated G-code of milling for a machine Haas VF-6, where a mold was made
