Subject of inquiry – process of a crimped lock and elastic-power performances of a machine vice with one and two kinematic chains at handling of prismatic parts on milling and work centers with a numerical direct numerical control. The operation purpose it is stabilization and heightening of elastic-power performances of clutches of type of a machine vice at minimum expenditures of power resources on the basis of development existing, synthesis of new progressive constructions and their theoretical and an experimental research, mining of a procedure of projection and account. Methods of examinations. Theoretical examinations were spent on the basis of up-to-date theories of synthesis and methods of a system approach, methods of mathematical model operation. Experimental researches were spent with use of specially designed technological equipment in laboratory and working conditions. It is theoretically proved and experimentally it is confirmed, that irregularity of rigidity from immovable and mobile tightening jaws of a machine vice influences their power performances; the mathematical model of the elastic-stressed state of system "vice-preparations" and the output analytical dependences of the net force of a crimped lock is developed; it is installed, that a frictional force in a loose port of a machine vice leads to magnification of the net force of a crimped lock in a time in cut; for the first time the implemented system approach to projection of clutches with several kinematic chains for a crimped lock of prismatic work pieces on an instance of a machine vice. The used morphological analysis, and also the offered morphological tables and matrixes for synthesis of a machine vice, designed procedures of projection of a machine vice with improvements in elastic-power performances. Effects of operation are injected into scientific process and mustered in the conditions of manufacture at the engineering factory.
