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.

Minimum Quantity Lubrication (MQL) has received much attention from the research community as a potential lubricating system to reduce environmental hazards and health issues that can be commonly found in flood cooling/lubricating systems based on metalworking fluids. The addition of nanoparticles MQL (NMQL) led improved machining performance, increasing cooling capability reducing friction tool wear, some researchers have proved applicability this type for difficult-to-cut materials. However, mist generated by due both itself operation may pose an additional hazard operators which is being overlooked community. These become more severe when using nanoparticles, but unfortunately very few works paid nanoparticle toxicity applied systems, issue should clearly understood before encouraging its implementation industry. Furthermore, current legislation does not help since regulation permissible exposure limits dealing with still ongoing most cases. In work, analyzed, recent studies vitro vivo presented. A relative comparison provided those been reported literature additives MQL. review focused analyzing main factors are identified size, shape, surface properties, agglomeration solubility. This presents guidelines safer nanolubricant formulations, guiding practitioners towards proper NMQL implementations occupational recommendations all potentially used interest terms work safety.
