This paper deals with the dimensional analysis of the turboprop aircraft engine radial compressor wheel. The radial compressor wheel is very complex component. This part is manufactured by turning and five-axis milling technology. Due to the high stress of this part in service life, the residual stress in the surface layer is important. Desirable are the compressive stress levels to prevent cracks. For this reason, research is being carried out on technologies that influence the surface layer. They are the finishing technologies vibrational tumbling and superfinishing. The article describes the method used to measure the thickness variation of blade of the compressor wheel after vibrational tumbling and superfinishing. In terms of shape complexity a coordinate measuring machine with a rotary table was used.
