magistrsko delo magistrskega študijskega programa II. stopnje Strojništvo
Abstract
V magistrski nalogi je predstavljena optimizacija frezalnih parametrov za trohoidno obdelavo. Cilj optimizacije je doseganje hrapavosti površine manj kot 0,8 µm pri maksimalni produktivnosti procesa. Material obdelovanca je aluminijeva zlitina AA 2007/EN AW 2007. Poizkuse frezalnih parametrov smo izvedli s pomočjo metode načrtovanja eksperimentov DOE za tri različna stebelna frezala, pri čemer smo spreminjali radialno globino, rezalno hitrost in podajanje na zob. V metodologiji so predstavljene lastnosti uporabljenega materiala, CNC obdelovalnega stroja, frezalnih stebelnih orodij ter postopek načrtovanja in izvedbe eksperimentov. V poglavju rezultatov so predstavljene meritve hrapavosti, optimizacija frezalnih parametrov ter stroškovna analiza za izbran izdelek. Ugotovitve so pokazale, da lahko z vsemi tremi orodji dosegamo željeno hrapavost vendar pri različnih produktivnostih procesa. Z analizo DOE in potrditvenih poizkusov smo prišli do spoznanja, da je orodje C najbolj primerno za doseganje željenih kriterijev. Pri obdelavi izdelka smo dokazali, da uporabljena tehnologija bistveno pripomore k zmanjšanju časa izdelave izdelka, ter posledično zmanjša obdelovalne stroške.

Secondary title: |
Trochoidal milling process parameters optimizations in mashining of aluminium alloy AA 2007/EN AW 2007 |
Secondary abstract: |
The master's thesis presents the optimization of milling parameters for trochoidal machining. The goal of optimization is to achieve a surface roughness less than 0.8 μm at maximum process productivity. The workpiece material is aluminum alloy AA 2007 / EN AW 2007. Experiments with milling parameters were performed using design of experiment method DOE for three different milling tools, which we were changing radial depth, cutting speed and feed per tooth. The methodology presents the properties of the used material, CNC machine tool, milling tools and the process of planning and performing experiments. The results section presents roughness measurements, optimization of milling parameters and cost analysis for the selected product. The findings showed that with all three tools we can achieve the desired roughness but with different process productivity. With DOE analysis and confirmatory experiments, we came to the conclusion that tool C is the most suitable for achieving the desired criteria. In the manufacturing process of the product, we have proven that the used technology significantly reduces the production lead time, and consequently reduces the processing costs. |
