GARCIA-GONZALEZ, José Antonio; JACAS-CABRERA, Mario; GALVEZ-GARDENTEY, José Carlos  and  -RIVER, Rene Pérez. Determination of cutting speed and feed rate in finished machinated of Babbitt metal. Ingeniería Mecánica [online]. 2018, vol.21, n.3, pp. 161-166. ISSN 1815-5944.

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.

Keywords : surface roughness; cutting speed; feed rate; Babbitt material; gliding bearing.
