Kinematic state of a working-piece at bulk metal forming of axialsymmetrical pieces has been determined in this paper. Strain rate tensor components
are determined by the known theory, as partial strain rate component devivations. Displacement rate points of meridial section are basic for kinematic state determination. As non-stationary deformation process is concerned, it is necessary to determine initial and final points displacements when a relatively short observed interval is constant. Point displacements are determined by known geometry of groovelike plates before deformation and measured coordinate points out of digitalized picture of meridial section after deformation. Measure meuts are done by setting the lines with
sufficient number of points. At the end, a graphic interpretation of the obtained results is given, their analysis and conclusions are made.
