Abstract Grinding could be used to enhance accuracy and quality of carbon fiber‐reinforced poly‐ether‐ether‐ketone (CF/PEEK) composites. However, the grinding mode, namely up‐grinding (UG) or down‐grinding (DG), is usually neglected while unbefitting mode choice may cause inferior surface quality.

Abstract As a more sustainable alternative to carbon fiber reinforced thermosetting (CFRTS) composites, thermoplastic (CFRTP) composites are increasingly being used favor the lightweight design and energy‐saving needs of new generation high‐end equipment. Usually, cutting is an essential manufacturing process for CFRTP components overcome preparation limitations meet assembly requirements. However, regarded as typical difficult‐to‐machine material, resulting in extremely poor machining quality efficiency. In this paper, comprehensive literature review on provided from three aspects. Firstly, chip formation, force, temperature described understand mechanism clearly. Secondly, influencing factors damage formation well detection methods summarized. Finally, improvement recent years, parameters, tools, assisted technologies, presented. Furthermore, conclusions future trends discussed, which offers significant reference value realization high‐quality efficient CFRTP. Highlights has attracted widespread attention equipment due its excellent mechanical properties environmental friendliness. Cutting components. mechanism, damage, method during reviewed. The current research gaps discussed.

Abstract As a key material in aerospace applications, carbon fiber reinforced polymer (CFRP) requires precision grinding to maintain the accuracy and integrity of assembly surfaces. However, machining damage remains significant technical bottleneck that affects service performance CFRP components. To address this, ultrasonic vibration‐assisted minimum quantity lubrication (MQL) with nanolubricants was developed. Despite this advancement, formation evolution under inherent random properties grains remain unclear. In study, instantaneous dynamic generation, conduction, accumulation heat, along its thermal effects, were examined. Additionally, 3D microscale three‐phase finite element numerical models established investigate mechanisms removal for different orientation angles (FOAs) using single‐grain grinding. Grinding experiments conducted evaluate distribution quantitatively compare effects vibration nanolubricant combinations. The results indicate vary FOA, complementing debris generation mechanisms. Damage is primarily distributed direction, lowest observed at 0° FOA highest 45° FOA. 2D ultrasonic‐assisted MQL 90° coupled angle ( θ U ) provided optimal reduction, achieving maximum decrease 27.56% compared conventional contrast, showed excellent suppression only 135° reduction 40.38%. This article provides theoretical support strategy Highlights Instantaneous investigated. mesoscopic mechanical–thermal FEM established. Mechanisms evolution, revealed. Distribution comparison damages characterized.
