Thin-walled elements are widely used in the aerospace industry, where aim is to reduce process time and weight of structure while ensuring sufficient quality finished product. Quality determined by geometric parameters dimensional shape accuracy. The main problem encountered during milling thin-walled deformation Despite various methods available for measuring deformation, more still being developed. This paper presents selected surface topography vertical an experiment under controlled cutting conditions samples from titanium alloy Ti6Al4V. Constant feed (f), speed (Vc,) tool diameter (D) were used. Samples milled using a general-purpose high-performance machining, as well two different machining approaches: with greater involvement face milling, cylindrical constant material removal rate (MRR). For thin walls, waviness (Wa, Wz,) roughness (Ra, Rz) measured contact profilometer areas on both processed sides. Deformations cross-sections perpendicular parallel bottom sample GOM measurement (GOM—Global Optical Measurement). showed possibility deformations deflection arrows proceeded measurement. Differences observed increased cross-section cut layer. A deviation 0.08 mm assumed was obtained.
