Thin-walled parts play a critical role across various industries. During the milling of thin-walled parts, the machining accuracy is heavily influenced by the milling method, which directly determines the milling forces involved. Milling force is one of the main characteristics of the milling process. To analyze and compare the milling forces across different machining methods, it is crucial to assess both the total force and its individual components, as they directly contribute to the elastic deformation of the thin-walled parts, thereby affecting precision and performance. The main objective of the presented method is the milling force components rearrangement by overlapping. This method enables the formation of complex microstructures on the surface, which is necessary for providing their tribological properties. The overlapping method permitted to reduce the milling force component by 1.69 times and deflection errors accordingly without additional fixture support or significant equipment parameters change. The modeling results evaluation of the generated force components, temperature, and stress, depending on the flank and overlapping milling methods, is presented for the equal input milling parameters. The relationship between the formed geometry and material removal rate is established. A decrease in milling force is observed at tool inclination angles of 15° and 30°.
