“…Since F a is almost zero and negligible, only the effects of F n and F t are analyzed in this study. [40,41] To make the experimental results more accurate, the average grinding force on the grinding-force curve in the stable processing phase was taken as the value of grinding forces with the corresponding experimental parameters. [29] Subsequently, the effects of different process parameters on the grinding forces generated during the grinding process of CF/epoxy and CF/PEEK can be obtained, as shown in Figure 4.…”

In order to distinguish the grinding performance of the thermoset and thermoplastic carbon fiber‐reinforced plastic (CFRP) composites, carbon fiber‐reinforced epoxy resin (CF/epoxy) and carbon fiber‐reinforced poly‐ether‐ether‐ketone (CF/PEEK) composites were employed in this study. Different process parameters were set to grind the two materials. Then the surface morphologies and roughness of the workpieces with different process parameters were observed and measured. Experimental results indicated that the grinding forces were positively correlated with the grinding depth and feed speed, and negatively correlated with the wheel speed. The grinding depth was the main influencing factor of the maximum temperature of the grinding. The heat distribution of the grinding process was dependent on the fiber direction. In addition, the chip formation mechanism of CF/epoxy and CF/PEEK were investigated. Compared with CF/epoxy, the grinding forces and temperature were higher and the wheel was more prone to be clogged under the same grinding parameters, indicating that it was more difficult to process CF/PEEK. However, the surface quality of CF/PEEK with high ductility was much better than CF/epoxy.

The research delves into the uncharted terrain of crystal orientation’s effect on high-frequency vibration-assisted processing of single-crystal copper, employing molecular dynamics to devise non-vibration, one-dimensional (1D), and two-dimensional (2D) vibration-assisted scratching models. The innovative discovery is the ‘peak-shaving’ effect, invoked by high-frequency vibration, which significantly mitigates surface irregularities on single-crystal copper, enhancing surface quality and material plasticity, thereby facilitating machinability. A key revelation is the superior efficacy of 2D vibration in material fortification relative to 1D vibration. Another novel finding is the amplified plasticity of single-crystal copper with a (111) crystal orientation under vibration-assisted excitation, linked to the varying directions of dislocation slip contingent upon crystal orientations. The pioneering observation that the induction of vibration during scratching dynamically propels dislocation defect structures, leading to the generation of a significant volume of vacant and interstitial atomic sites, underscores the pronounced influence of 2D vibration. This research contributes invaluable microscopic perspectives into the operative mechanism of crystal orientation’s impact on high-frequency vibration-assisted processing.

Due to its exceptional mechanical properties, 18CrNiMo7-6 alloy steel is one of the preferred materials for producing critical components of high-speed heavy-duty gearboxes. To study the relationship between cylindrical grinding parameters, i.e., workpiece speed, wheel speed and grinding depth, and grinding responses (grinding force, temperature and surface residual stress), dimensional analysis and finite element simulation of cylindrical grinding for 18CrNiMo7-6 alloy steel are performed. A mathematical model of grinding force and residual stress of cylindrical grinding is proposed, and the numerical and experimental verifications of 18CrNiMo7-6 cylindrical alloy steel are carried out. Numerical verification shows that the maximum relative errors of grinding force and residual stress models are 7.9% and 11.2%, respectively. The experimental results reveal that the maximum absolute errors were 1.31 N and 33.7 MPa, respectively. The results indicate that the proposed model could be used as a guide for practical grinding operation, which is helpful to optimize machining parameters, improve production efficiency and ensure high quality machining results.
