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.
