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