In this paper, heat transfer analysis during cutting 2024-T351 aluminium alloy with carbur tungsten (25° rake angle) and especially in 2, 3D orthogonal cutting operation numerically was performed. The assembly was modelled, meshed and analysed using commercial computational tool ABAQUS EXPLICIT. The parameters to be varied are depth of cut and impact speed, the thermal boundary conditions are adiabatic, the thermal contact between tool and workpiece is imperfect and the following method is Lagrangian, the results were well visualized and compared with literature, [23] and are in good agreement with reality of cutting. It was found that maximum temperature turn around 400°C when cutting and it is located in chip formation on the other hand, heat conduction with impact speed were two antagonist phenomenon, in other terms, increase in impact speed has less effect on heat transfer and in conduction espescialy.

D’aucuns nieront que parmi les essais définitoires attenants à la notion de littérature, son pouvoir à représenter la culture d’appartenance se présente comme un trait constant et transversal, d’où le leitmotiv qui stipule que la littérature est un réverbérant culturel par excellence. Dans le présent article, il serait question de mettre en lumière la prégnance de cette dimension culturelle dans la littérature orale en générale et parémique en particulier, étant donné que la transmission d’un grand pan de la culture lui incombe. Abstract: among the multiple defining traits of literature, we mention its ability to represent the culture it belongs to, from where the sempiternal leitmotiv which stipulate that the literature is the mirror of the culture. The present work, in an attempt to shed light on a cultural dimension to literature, tackles the oral literature and proverbial expressions. In this kind of literature, the cultural representation is the obligation of the proverbial expressions.
