Estudio de los parámetros de corte de planchas de acero ASTM A36, utilizando una sierra circular de cinta (Metal Band Saw-Modelo BS-1018B), en diferentes condiciones de lubricación, bajo criterios de sostenibilidad: corte de planchas de acero ASTM A36-Sin lubricación.

Abstract

This paper deals with the analysis of the feed rate and belt speed parameters suitable for cutting ASTM-A36 material specimens with a circular band saw model BS-1018B without the use of lubricant. This is done in order to determine the feasibility of applying this process to future work. Tests were carried out on test pieces of different sizes, varying the cutting parameters to obtain the roughness values of each test piece and determine the surface quality, in addition, a visual analysis of the chips obtained in each test was made and thus define the optimal values of the parameters that allow to have a good surface finish. With the data obtained in the tests, a statistical analysis was carried out with the help of the Minitab and Excel tools to find the influence of the cutting parameters with respect to the roughness obtained on the surface of the specimen, where it was evidenced that the speed of the tape is the factor that most influences obtaining the roughness. Finally, a comparison was made between the values obtained in the statistical analysis and the visual analysis where it was evidenced that the values are similar, concluding that the optimal values for cutting in the band saw without lubricant are Feed rate (Va) = 1 and 4 [mm/min] and Belt speed (Vc): 196 [fpm].
