“…The application of hydromechanical extrusion (hereinafter referred to as HE) enables one to create semi-fluid friction of the bar on the container walls and on the die mouth [1]; this provides a favorable action of friction forces since the lubricant velocity exceeds that of the bar [2]. Herewith, extrusion pressure and the degree of strain inhomogeneity decrease significantly, and the bar-tool contact decreases; this is particularly relevant for metals adhering to the tool [1,3].…”

An intelligent software system is developed for improving the process of hydromechanical extrusion enabling semi-fluid friction of the bar on the container walls and on the die mouth to be created, thus providing a favorable action of friction forces due to the fact that the velocity of the lubricant layer exceeds that of the bar. Herewith, extrusion pressure and the degree of strain inhomogeneity decrease significantly, and the bar-tool contact decreases, this being particularly relevant for metals adhering to the tool.

“…As was reported in [2,3], various CAD and CAE systems are used for the implementation of hydromechanical extrusion. Basic tool dimensions are container length and diameter, the taper angle and the length of the parallel land of the die, which were thoroughly discussed in [1][2][3].…”
