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.

Abstract

In this study, a comprehensive investigation was conducted to characterize the resulting surface quality of drilling operation on the VIWA VCM3M400 machining center. This was done by applying a specific combination of cutting parameters, including spindle rpm, drill feed rate, and various lubrication conditions, on ASTM A36 steel specimens. The evaluation and selection of optimal parameters were based on the analysis of machining time, surface roughness, and conicity of the pieces.

Initially, cutting parameters were determined based on the drill manufacturer's technical specifications and the machine's capabilities as per the user manual. Subsequently, initial tests were conducted to validate the applicability of the selected ranges, and final ranges for testing were established. The drilling process was designed and simulated using CAM-CAD software. Specimens were meticulously prepared, and tests were carried out by modifying the parameters of the G-code as necessary. During the experiment, the time of each operation was recorded, and upon conclusion, roughness and conicity measurements were taken.

The results obtained allowed the identification of optimal parameters that ensure a superior surface finish. Additionally, a guide table was developed, highlighting the most effective combinations for conducting a high-quality drilling process. This research provides a solid foundation for improving efficiency and quality in drilling operations on the VIWA VCM3M400 machining center.
