Analyzing cutting force and vibration amplitude in high-speed milling of SKD11 steel with thermal assistance

Abstract

In the realm of machining, the optimization of cutting conditions stands as a paramount pursuit for enhancing both efficiency and precision. This study embarks on a pioneering investigation delving into the intricate interplay among workpiece temperature, Thermal-Assisted High-Speed Machining (TA-HSM), cutting force dynamics, and vibration amplitudes during the milling process of SKD11 steel. Beyond a mere exploration, this research endeavors to unveil not only the impact of temperature and velocity on machining dynamics but also to delineate regions characterized by elevated temperature and velocity that exhibit the potential to mitigate cutting forces and vibrations, thereby refining machining methodologies. Experimental inquiries encompassing diverse temperature regimes, coupled with variations in cutting speeds, offer valuable insights into the nexus among temperature, cutting force and vibration amplitude. Of particular significance are the high-speed milling trials conducted under the most elevated admissible support temperature, which furnish elucidation on the ramifications of high speeds on cutting forces and vibrations. This inquiry constitutes a substantive contribution to the field by elucidating the correlation between cutting force and vibration amplitude under the thermal influence and high-speed milling within thermally demanding environments. Moreover, this study extends practical utility by proffering actionable insights into the optimal temperature range and cutting speeds requisite for effecting desired enhancements in machining productivity. By discerning and delineating these optimal parameters, this research endeavors to furnish tangible guidelines for practitioners seeking to optimize their machining processes, thus fostering advancements in both efficiency and precision within the machining domain.
