    Análisis de la influencia de un dieléctrico ecológico sobre la rugosidad superficial en el maquinado del acero K100 mediante el proceso de electroerosión por hilo (WEDM)

    In the Ecuador, non-conventional mechanized process have carried an analysis that is referred to the form of production of mechanic elements of complex geometry, that’s why the necessity of investigate the cuts of wire electroerosion (WEDM); using an alternative dielectric which is ecological in base to the electrochemical effect, for the aim of substitute the common way of coolant without the alteration of the final roughness and hardness on the cutting section, and preserve the equipment integrity, and contributing to the factories dedicated to the sheet metal process, to the ecology and the environment around us. The mentioned process goer together with the adequate cutting parameters study, based on an experimental investigation lead to characterized the representative ones of the surface finishing. The analysis is based on a comparative treatment which permits knowing the variability of the roughness and hardness acquired amounts on the cutting section through a variances analysis ANOVA about the factors that influence on the cutting process, in addition observe the presence of possible alterations on the cutting zone through the application of a scanning electron microscope (SEM). Having as a result the applicability of the alternative dielectric because under the influence of the same is achieved to obtain in average a significant value of roughness equal to 4,658 micrometers which is less to the achieved average amount with the application of the coolant, where the average is 5,253 micrometers. Furthermore, the surface represents less rate of irregularities, and one significant average to hardness it is referred. That is why the ecologic fluent gets to substitute easily, achieving with the asked expectations for the mechanized type.
