The expression for determining the angle of workspace stream atack to a point on the curvilinear surface of machine part during its strain prossesing is recieved. It allows estimate the distribution of kinetic energy supplied to the surface by a disjointed solids stream and intensity processing, therefore, to improve the process control and develop recommendations for carrying out the automation process.
