Taking the discrete degree of bearing raceway grinding surface integrity as research object, orthogonal test based on wheel speed, workpiece speed and depth is designed. The residual stress, retained austenite, hardness, modified layer thickness roughness after were measured, mean value standard deviation these indexes calculated. results show that stress decreases with increase hardness keeps ...

many graph theoretical parameters have been used to describe the vulnerability of communication networks, including toughness, binding number, rate of disruption, neighbor-connectivity, integrity, mean integrity, edgeconnectivity vector, l-connectivity and tenacity. in this paper we discuss integrity and its properties in vulnerability calculation. the integrity of a graph g, i(g), is defined t...

Manufacturing of hardmetal tools often involves surface grinding, ion etching and final coating. Each stage throughout the manufacturing chain introduces surface integrity changes which may be critical for defining the final mechanical behavior of the coated tools. Within this context, an experimental test program has been developed to assess the influence of a coating (TiN) deposition on surfa...
