Additive technologies implementation in the part design and production

Diplomski rad obuhvaća teorijsku razradu te praktičnu primjenu stečenih znanja s ciljem rješavanja problema zadanog zadatkom. U teorijskom su se dijelu rada obrazložili i opisali aditivni postupci, CAD i CAM aplikacije, prototipni inženjering te reverzno inženjerstvo. Osim toga teorijski je razređen kompletan postupak od skeniranja nekog predmeta pa sve do njegove izrade. Praktični je dio zadatka obuhvatio procese trodimenzionalnog skeniranja dijelova mehaničkog prijenosnika - reduktora, obrade podataka dobivenih skeniranjem, pretvorbe prikupljenih podataka u trodimenzionalne modele opisane značajkama te izradu fizičkih modela dobivenih korištenjem dvije metode aditivnih tehnologija izrade – metode ekstrudiranja i metode stereolitografije. Naposlijetku, korištenjem CAM programskog paketa kreirana je simulacija obrade strojnog dijela za računalno-numerički upravljani stroj – CNC stroj.Graduate thesis includes theoretical elaboration and practical application of acquired knowledge for solving the assigned task. Theoretical part covers and describes additive processes, CAD and CAM applications, prototype engineering and reverse engineering. In addition, the complete process from scanning of an object, all the way to its creation, has been theoretically elaborated. The practical part of the task consists of the process of 3D scanning speed reducer parts, processing of scanned data, transformation of data collected with scanning into 3D models described with features and production of those parts using two methods of additive manufacturing technology - extrusion methods and stereolithography methods. Finally, using the CAM software package simulation of machining process for one of the reducer parts has been created and prepared for machining on computer-numerical controlled machine - CNC machine
