Evaluación de los parámetros de mecanizado en el proceso de taladrado en el centro de mecanizado CNC bajo diferentes condiciones de lubricación : Diseño y fabricación de agujeros por taladrado CAM-CNC – Con Lubricación.

Abstract

This research focuses on evaluating machining parameters during the drilling process on a CNC machining center. Twenty-seven drills were performed on AISI 4140 steel specimens using a VIWA CNC machining center, model VCM3, equipped with a CENTROID M400 AC controller and a 12.5 [mm] diameter 5% cobalt IZAR drill bit. The 27 specimens were fabricated by combining different levels of cutting speed, lubrication flow rate, and depth of cut, varying these parameters at high, medium, and low levels using a 3k experimental design. In each experiment, roughness, diameter, and cycle time were measured using a roughness meter, caliper, and the CENTROID controller, respectively. The collected data allowed identifying trends between cutting parameters and the measurements taken. Optimal conditions were analyzed to achieve the best surface roughness, IT quality, and more efficient cycle time. Finally, the optimal combination of parameters was determined to achieve an overall improvement in the surface and dimensional quality of the drilling process under these conditions, ensuring acceptable cycle times.
