Correlation Analysis between Tool Wear, Roughness and Cutting Vibration in Turning of Hardened Steel

Youcef ABIDI & Lakhdar BOULANOUAR
Hard machining is a process that has become highly recommended for replacing grinding in the manufacturing industry . This is due to its ability to machine complex shapes with reduced production costs by reducing the machining time and being an ecological process. Three technological parameters determine the quality and productivity generated from this process: cutting vibration, surface roughness and tool wear. Therefore, the analysis of the correlation between them is very important. In the present...

Data from: High genetic diversity and distinctiveness of rear-edge climate relicts maintained by ancient tetraploidisation for Alnus glutinosa

Populations located at the rear-edge of a species’ distribution may have disproportionate ecological and evolutionary importance for biodiversity conservation in a changing global environment. Yet genetic studies of such populations remain rare. This study investigates the evolutionary history of North-African low latitude marginal populations of Alnus glutinosa Gaertn., a European tree species that plays a significant ecological role as a keystone of riparian ecosystems. We genotyped 551 adults from 19 populations located across North Africa...

Data from: Microsatellite length variation in candidate genes correlates with habitat in the gilthead sea bream Sparus aurata

Lamya Chaoui, Pierre-Alexandre Gagnaire, Bruno Guinand, Jean-Pierre Quignard, Costas Tsigenopoulos, M. Hichem Kara & Francois Bonhomme
The genetic basis and evolutionary implications of local adaptation in high gene flow marine organisms are still poorly understood. In several Mediterranean fish species, alternative migration patterns exist between individuals entering coastal lagoons that offer favorable conditions for growth and those staying in the sea where environmental conditions are less subject to rapid and stressful change. Whether these coexisting strategies are phenotypically plastic or include a role for local adaptation through differential survival needs to...

Mathematical Simulation of Heat Generation at a Cutting-Tool Surface During Stock Removal Processes

Hocine MZAD
The heat generated in various cutting zones significantly influences machining, affects tool wear, and thereby reduces tool life. In this paper, a spline cubic interpolation is used to estimate the transient heat flux imposed on the surface of a carbide cutting tool during stock removal, at constant thermal properties and cutting velocity. Interpolation of instantaneously measured temperature data set by the polynomial of lowest possible degree that passes through the points of the dataset is...
