INFLUENCE OF THE ANGLE OF LEAD OF WEDGE SPIRAL LEDGES OF THE MATRIX ON POWER AND DEFORMATION PARAMETERS OF THE EXTRACT WITH LOCAL THINNING
Computer modeling of process of an extract with local thinning of a wall of preparation in a matrix with mnogozakhodny spiral ledges on perimeter of a working corbel is executed. The analysis of influence of an angle of lead of spiral wedge ledges of a matrix at sizes of technological force, intensity of tension and intensity of deformations is made.
