Object of research: resource-saving processes and tool for plastic molding of blanks and parts with holes. The purpose of the work is to increase energy and resource efficiency and to expand the possibilities of technologies for manufacturing blanks with blind and through hole type sleeves and rings of high quality due to the use of new deformation schemes with combined kinematic impact on the workpiece during extrusion. Research methods - morphological map method, finite element meth-od, upper estimation method, power balance method, dividing grid method. Theoretical and practical results - breaking up new and more precise mathematical models for the process of a combined after-day view with crimped and confused view on the basis of a modular approach; a preliminary analysis of the deposits of the given vise on the finished product was carried out, on the basis of the new func-tions, and to describe the curvature between the new tricut module; carrying out the analysis of a non-lead-free method of making parts of the bushing type on the basis of simple stitching; vivcheni regular-ity development of the stressed-deformed mill of parts of the type of ring; The results of the modeling of the process of cold hot stamping of empty virob from low-carbon steel with intensive plastic defor-mation of the wall for obtaining the necessary mechanical powers are given. Novelty - the complex of mathematical models of the processes of precise stamping of workpieces and the establishment of the deposition of the power regime and technological and design features to the process of shaping, which are perceived to be real described in the middle of the deformation and leakage of metal; New kine-matic modules of tricot form are pro-proponated, which allow the model of force mode in the process-es of large-scale deformation and description of the mid-point of deformation of the older configura-tions. Scope - metal processing by pressure, open die forging, forging of large forgings.
