Investigation of the structure of complex surfaces of parts after shot blasting

The article shows that in order to determine the parameters of the surface structure, it is necessary to use optical research methods. An optoelectronic complex has been developed that allows determining the amplitude and average step of the correlation surface depending on the modes and conditions of shot blasting. A measurement technique and a software package for determining the parameters of the surface structure are proposed. The identification of structural parameters with the roughness parameters of complex surfaces was carried out.
