摘要

Deep hole components are widely used in important fields such as military equipment, aerospace, and energy equipment. Boring, as a key process in deep hole machining, often faces challenges such as boring bar chatter, tool wear, and difficulties in errors measurement during operations. This paper reviews the current research on chatter suppression for boring bars, tool wear monitoring, and deep hole error measurement. Regarding chatter suppression methods for boring bars, this paper focuses on the design of active and passive damping boring bars and reviews the chatter detection techniques used in active damping systems. Subsequently, the paper discusses tool wear monitoring methods based on mechanism models and data-driven models. In addition, the paper analyzes contact and non-contact measurement methods for assessing dimensional and shape errors in deep holes. Finally, the paper explores future trends in deep hole machining technology, including the use of shear-thickening fluid (STF) as a novel damping material in damping boring bars, the integration of chatter mechanisms with data-driven chatter detection techniques, the application of digital twin technology in tool wear monitoring, and the use of on-machine measurement and error compensation in deep hole error measurement. This review summarizes the challenges faced in deep hole boring and provides insights for achieving high-quality and efficient deep hole machining.
