Experimental Studies on Bending Cardboard by Pushing It Through a Matrix

A research stand has been developed to conduct research on the phenomena that accompany the bending of cardboard / paper during the manufacture of the bottom part of food containers and containers. A universal experimental stand for studying the pro­ perties of corrugated cardboard has been adapted to another material – folding card­ board; a program of experimental research has been developed aimed at determining the linear specific load when bending a flat material by 90 degrees perpendicularly and across paper fibers.

Computer 3D modelling of chip geometry and force field in the hobbing process

Nowadays, the main method of machining the gears with a module in the range 1–25 mm, which are integral parts of modern machines, remains hobbing. Operations of the toothed crown processing determine the efficiency of the entire technological process of manufacturing gears. Thus, the time expenses and performance, the cost of the gears, and their final quality depend to a large extent on these indicators in operations of hobbing.

Interrelated processes of local electric field amplification in solid dielectrics, contributing to their degradation

The complex processes of local disturbance of an electric field, as well as the amplification of electrical strength and mechanical and thermal intensities in the solid dielectric, depending on the configuration of its conducting micro-inclusions are described.
