CAM programming of 3-axes CNC milling machine

Zadatak ovog diplomskog rada može se podijeliti u dva dijela odnosno na teorijski te praktični dio. U teorijskom dijelu rada prikazan je pregled osnovnih karakteristika i podjela alatnih strojeva s posebnim osvrtom na glodalice i obradne centre. U nastavku teorijskog dijela također je prikazana podjela postupka sve popularnije aditivne proizvodnje te njezina usporedba sa konvencionalnom obradom. Pri samom kraju teorijskog dijela, dati je kratak opis Darrieus -ove vjetroturbine. Praktični dio rada sastojao se od izrade lopatica vjetroturbine koristeći postupke aditivne proizvodnje te postupak glodanja. Prototip lopatice izrađen je koristeći FDM tehnologiju, dok su finalne lopatice izrađene PolyJet postupkom. Kao uvjet za drugi dio praktičnog dijela rada potrebno je bilo razraditi tehnološki postupak izrade lopatice te kreirati NC program primjenom Mastercam softvera za upravljačku jedinicu Heidenhain. Nakon virtualne provjere dobivenog NC programa, projektirana je stezna naprava te je izradak fizički izrađen koristeći troosnu CNC glodalicu.The task of this final work can be divided into two parts or into theoretical and practical part. The theoretical part of the final work presents a basic description of the characteristics and division of machine tools with special reference to milling machines and machining centers. The theoretical part also shows a importance of additive manufacturing and compares it to conventional machining. At the very end of the theoretical part, a brief description of Darrieus wind turbine is given. The practical part of final work consisted of making blades for wind turbines using additive manufacturing methods and milling process. The blade prototype was made using FDM technology, while the final blades were made using the PolyJet process. As a prerequisite for the second part of the practical part of the work, it was necessary to design a technological procedure for making a blades and to create an NC program with Mastercam software for managing the Heidenhain control unit. After a virtual check of the NC programs obtained, the fixturing device was designed to make physical blades using a three-axis CNC milling machine
