INFLUENCIA DE DIFERENTES TÉCNICAS DE LUBRICACIÓN EN EL ACABADO SUPERFICIAL EN OPERACIONES DE FRESADO DE ACEROS AL CARBONO

Abstract

In machining processes the use of coolants and lubricants in the cutting zone is critical to reduce cutting forces, facilitate the chip removal and improve the surface quality of the workpiece. However, the influence of different coolant/lubricant techniques on the surface finish depends on many factors, such as the geometry of the cutting tool, material of the workpiece, cutting conditions, and so on. This paper studies the effect of different lubrication techniques such as: internal coolant, external coolant, dry cutting, air coolant and MQL lubrication (Minimum Quantity Lubrication) on the surface finish and the advantages and disadvantages of these systems for milling carbon steels. The study fundamentally analyzes the variations in roughness due to the built-up edge (BUE) and the minimum chip thickness in relation to the type of lubrication / cooling used.
