Abstract

V magistrskem delu je predstavljena študija, kako različne strategije obdelave vplivajo na kakovost površin, na konkretnem izdelku-turbini. Osredotočena je na dve strategiji in sicer na t.i. točkovno strategijo frezanja, ki je primerna bolj za razgibane, proste površine in na bočno strategijo frezanja, idealno za turbinske lopatice. Izdelali smo CAM program in s pet osno obdelavo izdelali turbino. Za končno fino obdelavo lopatic smo uporabili omenjeni strategiji frezanja. Optimizirali smo parametre obdelave, da bi se kar se da približali teoretični hrapavosti površine. Primerjali smo izmerjeno hrapavost in čase obdelave. Ugotovili smo, da z bočno strategijo frezanja dobimo bolj kakovostno obdelano površino in krajši čas obdelave na primeru turbinskih lopatic. Podali smo tudi smernice za učinkovitejšo več osno obdelavo razgibanih prostih površin.

Secondary title:	Analysis of 5 axis machining strategies on quality of machined surface
Secondary abstract:	This master's thesis presents a study of how different milling strategies affect the quality of surfaces on a specific product-turbine. It focuses on two strategies, point milling strategy wich is more suitable for varied, free surfaces and a flank milling strategy, ideal for turbine blades. We created a CAM program and made a turbine with 5 axis machining. We used flank and point milling strategy for finishing passes of the turbine blades. We optimized the milling parameters to get as close as possible to the theoretical surface roughness. Then compared the measured roughness and milling times. What we found is that with a lateral milling strategy we get better quality of machined surface and shorter machining time in the case of turbine blades. We also provided guidelines for more efficient multi-axis processing of varied free surfaces.
