The technique of the analysis of uniformity of formation of a blanket is given in article in the course of vibroshock hardening by means of spline three-dimensional modeling. As the analyzed technological parameter the arithmetic-mean height of microroughnesses of a surface of Rz is used. The tool environment is presented by a final set of the particles moving under the influence of vibrating walls of the container in which it is. Dynamics of the tool environment is modelled by the method of discrete elements (MDE) on the basis of use of multinuclear parallel computers and 3D - videocards on the basis of the hardware-software NVidia CUDA platform. Three measured model of a strengthened detail is presented by a set of elementary triangular platforms – splines. Particles of the tool environment, colliding with splines of a surface of a detail, change their technological properties. Formation of a new condition of a blanket is in such a way modelled. Studied detail is the driving wheel of the compressor having a difficult three-dimensional form and a spatial arrangement of working surfaces. The special attention is paid to uniformity of processing of flowing channels. Results of numerical experiments on research of a roughness of Rz of the driving wheel of the compressor at existence and lack of rotation of a detail round its pivot-center are given.
