Abstract
The necessary deformation force represents one of the most important elements for applying the rolling method and for designing the technology and the suitable technological equipment. For this reason, the researches of the influence of deformation forces and their evolution during a processing cycle over the elements of technological system are very useful for the designers of the processing process. The conclusions reached offer concrete information about the way of plastic deformation development in correlation with constructive and functional features of the technological system elements: machine-tools, workpiece, roll tool.
