Today, machine tools play a vital role in the production of parts any manufacturing industry. The dimensional accuracy and surface finish work piece depends mainly on condition machine. Vibration occurring has been being serious problem for engineers many decades. Undesired relative vibrations between tool work-piece jeopardize quality surfaces during cutting.
 Many Condition Monitoring Te...

A method of multi-nomenclature production in terms technical and economic indicators was considered. An integrated design system that is able to assess the real relationship “partmachine-transport device-device-tool” proposed, arelationship between elements an automated machine tool examined. The structure system, proposed form a mixed graph, represented by sets described nonlinear equations, d...

Some microbes, among them a few species of cyanobacteria, are able to excavate carbonate minerals, from limestone to biogenic carbonates, including coral reefs, in a bioerosive activity that directly links biological and geological parts of the global carbon cycle. The physiological mechanisms that enable such endolithic cyanobacteria to bore, however, remain unknown. In fact, their boring cons...
