Aditivne tehnologije omogočajo s slojevito gradnjo fleksibilno izdelavo izdelkov kompleksnih oblik. Obstoječe tehnologije 3D tiska z uporabo prahov so pogosto počasne, drage in omejene na manjše gabarite izdelkov. Dodatno neustrezna hrapavost površin in natančnost izdelave običajno zahtevata naknadno mehansko obdelavo na dragih obdelovalnih centrih. V magistrskem delu je predstavljen razvoj alternativnega sistema kombinirane aditivne izdelave s postopkom robotskega navarjanja MIG in frezanja aluminijeve zlitine AlSi5. Sistem je v magistrskem delu analiziran na reprezentativnem kosu turbinske lopatice. Kot rezultat dela je dokazano, da razvit kombiniran postopek omogoča, v primerjavi z ostalimi aditivnimi tehnologijami, ekonomsko in produktivnostno alternativo na trgu pri izdelavi kompleksnih izdelkov.

• Title: A process of robotic layered welding and milling of aluminium alloy AlSi5

Abstract

Additive technologies enable flexible manufacturing of complex shaped products layer by layer. Existing 3D printing technologies, which use powder filler material are often slow, expensive and limited to smaller dimensions of the products. Inadequate surface roughness and low precision of manufacturing usually require subsequent machining, using expensive machining centers. In the following master's thesis the development of an alternative system for combined process of robotic wire and arc additive manufacturing using MIG welding and milling of aluminium alloy AlSi5 is presented. The system is analyzed on a representative turbine blade piece. As a result of the work, it has been proven that the developed combined process enables, in comparison with other additive technologies, an economical and productive alternative to the market in the production of complex parts.
