Abstract
The use cases of the mathematical model for ceramical materials drawing are proposed for computer-assisted design of the shape-generating apertured molding tools for screw extruders. The method of definition of both parameters for the pressable material plasticity function and the friction coefficients of materials against the tools surface is developed with the using of industry equipment. The yielding flow condition of materials through different kinds of tools which have straight lines as generators for working surfaces are analyzed. It is shown how it is possible by changing the channel’s surface shape, the drawing ratio in the local decreasing zone of channel cross section, and the bar forging’s cross section to select the optimal configuration for all these parameters.
