Evaluación Experimental del Desempeño del Proceso de Fresado Frontal del Acero ABNT 1045 para Herramientas con Diferentes Números de Aristas

Abstract

Experimental factorial design, with three replica and 95% of confidence, has been used for evaluating the asymmetrical face milling of ABNT 1045 steel. Two levels of cutting speed, two levels of position angle and three levels of cutting edges were employed. Feed rate and cutting depth were maintained at a constant value so the same volume of material in each test is removed. The results showed that the power consumed increased as the position angle was reduced, due to the increase of the specific cutting resistance by distributed shear force over the transversal section of the cutting tool. It is concluded that the variables studied have influence on the results and that they are interrelated in the process of asymmetrical frontal milling.
