Abstract

El objetivo de esta investigación fue la determinación la velocidad de corte y velocidad de avance para lograr durante el maquinado de acabado en material BABBITT (AVE-F1) de las chumaceras de apoyo de los ejes de las turbinas y las de los ventiladores de tiro forzado una rugosidad superficial de Ra menor o igual de 0,8 μm, durante  un proceso de mandrilado. Se realizaron 12 experimentos en seco, con cuatro niveles de velocidad de corte y tres de velocidad de avance, con una herramienta de HSS. La medición de rugosidad se realizó con un rugosímetro digital Mitutoyo. Como resultado final se observó la gran influencia de las variables de corte analizadas en la rugosidad superficial, obteniéndose valores de Ra iguales a 0,71 µm, con velocidad de  avance y velocidad de corte de (0,025 mm/rev; y 47 m/min) respectivamente. 

Palabras claves: rugosidad superficial, velocidad de corte, velocidad de avance, chumacera, metal anti fricción Babbitt.

Abstract

The aim of this research was to the determination of the of cutting speed and feed rate to achieve during the finished machined  in Babbitt material (AVE-F1)  of the bearings in support of the shafts of the turbines and those of forced draft fans a surface roughness of Ra less than or equal to 0,8 μm, subjected to a boring process.During a process of bored. 12 dry experiments were carried out, with four levels of cutting speed and three feed rate, with an HSS tool. The surface roughness was measured in Ra units [µm], using a MITUTOYO roughness meter. As a final result, the great influence of the cut variables analyzed in the surface roughness was observed, obtaining values of Ra equal to 0,71μm, with feed rate and cutting speed of (0.025 mm / rev, and 47 m / min) respectively.

Key words: surface roughness, cutting speed, feed rate, Babbitt material, gliding bearing.
