Resumen


During the machining process there are some factors which determine cutting tool wear, among the parameters most well known are cutting tool speed, feed, cutting deep, tool geometry, part”™s material structure to be machined. Due to the diversity of technological parameters involved in the machining process, the machinability of the deferent material has been researched by a lot of researchers. In this paper it is presented a new methodology to evaluate the machinability in turning steel marked as SAE 1020 produced in Venezuela. The procedure and material utilized are also described. The results were analyzed ac- cording to: data sheets and evaluation of tool life data, which belong to ISO 3685:1993 standard. With the experiments the tool wear was obtained just in time for three different speed values, and C”™s Taylor for the same time unit was calculated. Surface quality and chip type were also analyzed.
