Evaluación de los parámetros de mecanizado en la fabricación de roscas en ejes de acero AISI 4140 usando equipos cnc bajo diferentes condiciones de lubricación: mecanizado con lubricación.

Abstract

Obtaining results by making 54 AISI 4140 steel test tubes through the use of lubricatiion and without it, affects its operation and quality at the end of the process, for which three study parameeters have been selected: SANDVIK, ISO DIN 13 and constants, varying the spindle speed at 800, 550 and 300 [RPM] to obtain a general test of which parameter during the threading process is effective in which it is expected to obtain a specimen without undulations on the flanks, with a excellent finish. The process is carried out with the machines of the LABINTECDIMP of the National Polytechnic School, for which a estudy is carried out for the correct selection of parameters and tools through the use of standards and manufactur's catalogs. The preparation of the specimens is carried out in the machine tools laboratory and the threading is carried out in the ROMI C420 CNC Lathe, thus obtaining alternatives that help improve productivity, the quality of threading and the useful life of the insert during the process, machining process.
