Estudio de los parámetros del proceso de Taladrado de planchas de Acero ASTM-A36, en Centro de Mecanizado CNC, con diferentes condiciones de lubricación, bajo criterios de sostenibilidad : Sin Lubricación

Abstract

The primary aim of this Curricular Integration Project is to analyze and determine the most suitable combination of machining variables, specifically Spindle Speed (n) and Feed Rate (f_n), to establish effective test parameters for drilling 12 [mm] thick ASTM A36 Steel plates. The machining operations are conducted on the VIWA VCM3M400 Machining Center, which is equipped with a CENTROID M400AC controller, and lubrication is omitted for this process. To achieve this goal, the Latin Experimental Method 5x5 is implemented, which involves exploring the two machining variables across five distinct application levels. These levels span from the highest critical values to the lowest welcoming values, resulting in 25 potential combinations (experiments) for comprehensive analysis. Starting with the recommendations provided by the Cutting Tool manufacturer, the application levels of the machining variables are established. A ½ inch cobalt drill bit from DEBOR GERMANY brand is utilized for the drilling operations on ASTM A36 Steel plates. Test parameters, including Surface Roughness (Ra), Machining Time, and Dimensional Tolerance, are meticulously measured using laboratory equipment such as the Mitutoyo SJ-210 roughness meter, digital stopwatch, and Mitutoyo caliper. The analysis encompasses various aspects, including Roughness Grade, Time, Conicity, and Tolerance Quality. Ultimately, the study seeks to identify the most optimal combination, with a particular emphasis on achieving the optimal Dimensional Tolerance, which is crucial for machining operations.
