Damping investigation in boring bar using hybrid copper-zinc particles

Abstract: Particle damping is one of the promising damping techniques in effectively suppressing chatter in boring process. In earlier studies, granular particles are packed with the single particle type used to suppress chatter. This paper attempts at a novel hybrid approach in particle damping to increase the effectiveness of chatter suppression and enhance the machining stability. In this hybrid approach, Copper and Zinc particles are used together in equal proportion for packing inside the boring bar. The study find… Show more

“…Looking at the research regarding internal turning and dynamic stability or tuned mass dampers conducted up until now reveals that much research is focused on tools with diameters of 16 mm or more, as shown in Figure 1. This graph was plotted as an overview of individual research focusing on the field of machining with boring bars [2,[11][12][13][14][15][16][17][18][19][20][21][22][23].…”

“…As the impact and friction dampers placed on the surface of the boring tool cause damage to the machined surface resulting in reduced surface roughness and tool life. Biju Shunmugam [19], Chockalingam et al [20] and Diniz et al [21] developed boring bar with particle impact dampers (PIDs), where particles placed inside the cavity of the tool for stability improvement by controlling the vibrations in internal turning. The momentum was transferred from the primary system to particles, and increased energy dissipation caused by the collision of the particles and cavity walls minimized the boring bar's vibrations.…”

“…The stability lobes were shifted to the left side when the applied voltage increases. Further, Chockalingam et al (2017) used hybrid copper-zinc particles to suppress chatter in boring operation and observed an improvement in damping characteristics compared to the unmodified tool.…”
