Tribological Behavior of PVD Hard Coated Cutting Tools under Cryogenic Cooling Conditions
Article dans une revue avec comité de lecture
Cryogenic assistance is used to improve machining performance and to enhance tool life under extreme contact conditions (pressure and temperature). This paper focuses on the influence of cryogenic cooling conditions using liquid nitrogen within the context of machining Ti6Al4 V with CrN-coated carbide cutting tools. Friction behavior of both CrN-coated and uncoated pins with and without cryogenic cooling were evaluated using a home-made laboratory tribometer. The adhesive and plastic friction coefficients were evaluated using a finite element model of the pin-Ti6Al4 V system through an inverse methodology. Finally, the contribution of the CrN coatings was evaluated under both cryogenic cooling and dry conditions.

Phenomenological study of multivariable effects on exit burr criteria during orthogonal cutting of AlSi alloys using principal components analysis Article dans une revue avec comité de lectureRÉGNIER, Tristan; FROMENTIN, Guillaume; D'ACUNTO, Alain; OUTEIRO, José; MARCON, Bertrand; CROLET, Arnaud (American Society of Mechanical Engineers, 2018)During machining, burrs are produced along a part’s edges, which can affect a final product lifetime or its efficiency. Moreover, time-consuming and expensive techniques are needed to be applied to remove such burrs. ...
