But existing solutions either require explicit knowledge of externality variations which is typically unavailable or they render the part unusable due to infeasibly slow defect mitigation. This work addresses this issue by establishing a novel Conditional Reinforcement Learning (ConRL) approach for rapid and real-time data-driven defect mitigation based on an implicit consideration of externality variations. Validation within a smart manufacturing pipeline on a Fused Filament Fabrication testbed reveals the unprecedented ability to mitigate defects at 10× greater speed via a single control action and within the same printed line. A hitherto unreported degree of scalability is observed, i.e., it is possible to mitigate defects induced by untrained-for, unknown and unmeasured externality variations without any retraining of the policy. The results also reveal new insight into the significance of conditionality in ConRL and of real-time defect quantification.

Furthermore, the evolution of blood droplets on the micropillar array surfaces was investigated in direct/alternating current (AC) electric fields. Structural gaps enabled electrolysis-generated gases to escape downward, preventing blood expansion. Because of the oscillatory effect, AC excitation changes the blood droplets' morphology, which drives the gas–liquid interface toward the multicracked substrate; however, trapped gas impedes this negative behavior.

Firstly, some dominant points are selected according to cubic polynomial fitting error. Subsequently, an initial NURBS curve is generated iteratively. During each iteration, new dominant points are added, and the parameters of the tool tip points are updated. Finally, an edge error estimation method for NURBS curves is proposed and integrated into a regional optimization scheme to generate the resultant NURBS curve under geometric deviation constraints. Simulation and experiment results demonstrate that the proposed method can reduce the number of control points and curvature extreme of the resultant NURBS curve compared with the reference method. Furthermore, our method streamlines the interpolation process, resulting in time savings ranging from 10.66 % to 17.30 %, all the while adhering to the same geometric and kinematic constraints.

To tackle this issue, this study presents a prediction method for residual stress based on a unified thermo-mechanical computational unit with discrete abrasive grains, capable of predicting the grinding residual stress field with intricate details. In the calculation process, the heat flux modeling and the grinding force modeling of different grinding stages are unified innovatively, and the theoretical derivation of the micro-scale detailed grinding zone temperature is achieved. Moreover, an innovative analytical method for thermal and mechanical stress based on individual grains is developed, taking into account the effects of discrete abrasive grains and their grinding stages, with a unified calculation unit for grinding residual stress. The accuracy of the suggested method is confirmed by using the generating grinding of face gear, achieving an error rate of no more than 14.24 %. The results show that the grinding temperature field and the mechanical-thermal residual stress not only have the characteristics of nonlinear, discrete and locally closed, but also regionally and unevenly distributed.
