The article presents comparative research on the effects of milling of concave corners of elements made of aluminum alloy 7075. The work focuses on the study of the impact of changes in technological parameters and types of machining on the obtained geometrical state of the machined samples. Correct milling of the corners requires selection of the appropriate feed rate and the proper engagement angle of the milling cutter. At the corners, tool engagement angle increases, which significantly hinders the execution of stable machining and adversely affects the geometric and qualitative characteristics of the surface in the corners. Study with application of various strategies and technological parameters of milling corners with variable opening angles were carried out. The main parameters of surface roughness of the machined elements were examined. When analyzing the results obtained, conclusions were formulated indicating the relationship between the change of selected technological parameters, with the assumed type of treatment, and the obtained quality parameters of the samples made.
