This article presents a study of the compaction process of aluminium alloy chips from a physics-based perspective, focusing on the mechanical behaviour and physical parameters that govern material densification. The research involves experimental analysis of the force-density relationship during uniaxial compaction, with particular attention paid to the role of chip geometry, material fragmentation, and briquette diameter. The compaction process is interpreted through the lens of applied physics, considering stress distribution, particle rearrangement, and changes in bulk density. The results offer insights into the fundamental physics of deformable metallic systems and contribute to the development of efficient, physics-driven approaches to metal waste reduction in machining operations. The findings have potential applications in materials science, solid-state physics, and environmentally oriented industrial physics.
