Any product must undergo precise manufacturing before use.The damage incurred during the manufacturing process can significantly impact the residual strength of the product post-manufacturing.However,the relationship between residual bending strength and manufacturing-induced damage remains unclear,despite being a crucial parameter for assessing material service life and performance,leading to a decrease in product performance reliability.This study focuses on investigating the impact of crack generation on residual bending strength through theoretical and experimental analyses of scratching,grinding,and three-point bending.The research first elucidates the forms and mechanisms of material damage through scratch experiments.Subsequently,using resin-bonded and electroplated wheels as case studies,the influence of different process parameters on grinding damage and residual bending strength is explored.The reduction of brittle removal can lead to a 50%–60%decrease in residual bending strength.Lastly,a model is developed to delineate the relationship between processing parameters and the residual bending strength of the product,with the model exhibiting an error margin of less than 11%.This model clearly reveals the effect of crack generation under different process parameters on residual flexural strength. 展开更多

Fiber-reinforced silica ceramic matrix composites(SiO2 f/SiO2)have gained extensive attention in recent years for its applications in aeronautics field such as radar radome and window.However,the machining properties and mechanism of the material remain unclear.The features and mechanical properties of the material itself have a significant influence on both its machining characteristics and surface integrity.Thus,a full-factor grinding experiment is conducted using a 3 D orthogonal SiO2 f/SiO2 aiming to obtain its machining characteristics.The effects of grinding parameters and tools on the grinding force,surface roughness,and material damage type are investigated using a dynamometer,Scanning Electron Microscope(SEM),and Acoustic Emission(AE)analysis.The AE frequency band is analyzed,and a semi-analytical force model is established to study the difference between a single grain and wheel grinding.It was found that the changes in surface roughness correlate with the changes in grinding force,with fiber fracture being the main reason behind the increase in grinding force.Finally,the material removal mechanism was studied based on the AE analysis.It was found that the removal mechanism is fiber fracture dominated with matrix crack and debonding,and the primary sources of energy consumption are fiber fracture and friction. 展开更多

Precision and low damage grinding of aviation optical elements can effectively improve the overall processing efficiency.The mechanism of high-speed cross scuffing of multiple abrasive particles has become an important factor affecting the forming quality of workpiece.Interaction of abrasive trajectory determines machined surface and subsurface morphology and damage.According to the relative motion trajectory of wear particles on the workpiece surface,a theoretical model of the trochoidal trajectory intersection angle is proposed.High-speed scratches with different cross angles are experimentally obtained to explore the interference mechanism and damage accumulation of cross scratches.The results indicate that the Crack system I and Crack system II,produced by the two cross scratches,are mainly based on the stress principle and the strength principle,respectively.An increase in the damage radius is observed with a decrease in the crossing angle.Furthermore,as the duration of the normal cutting force decomposition curve at the entrance/exit of the intersection increases,the half-peak width also increases.The accumulation of cross-scratch damage promotes the propagation of deep subsurface lateral and median cracks.In other words,damage accumulation and interference mechanism formed by the cross scratches increase the longitudinal depth and lateral length of the damage. 展开更多

Vibration-assisted grinding is one of the most promising technologies for manufacturing optical components due to its efficiency and quality advantages.However,the damage and crack propagation mechanisms of materials in vibration-assisted grinding are not well understood.In order to elucidate the mechanism of abrasive scratching during vibration-assisted grinding,a kinematic model of vibration scratching was developed.The influence of process parameters on the evolution of vibration scratches to indentation or straight scratches is revealed by displacement metrics and velocity metrics.Indentation,scratch and vibration scratch experiments were performed on quartz glass,and the results showed that the vibration scratch cracks are a combination of indentation cracks and scratch cracks.Vibration scratch cracks change from indentation cracks to scratch cracks as the indenter moves from the entrance to the exit of the workpiece or as the vibration frequency changes from high to low.A vertical vibration scratch stress field model is established for the first time,which reveals that the maximum principal stress and tensile stress distribution is the fundamental cause for inducing the transformation of the vibration scratch cracking system.This model provides a theoretical basis for understanding of the mechanism of material damage and crack propagation during vibration-assisted grinding. 展开更多

An on-machine measuring(OMM)system with a laser displacement sensor(LDS)is designed for measuring free-form surfaces of hypersonic aircraft’s radomes.To improve the measurement accuracy of the OMM system,a novel Iteratively Automatic machine learning Boosted hand-eye Calibration(IABC)method is proposed.Both the hand-eye relationship and LDS measurement errors can be calibrated in one calibration process without any hardware changes via IABC.Firstly,a new objective function is derived,containing analytical parameters of the handeye relationship and LDS errors.Then,a hybrid calibration model composed of two kernels is proposed to solve the objective function.One kernel is the analytical kernel designed for solving analytical parameters.Another kernel is the automatic machine learning(AutoML)kernel designed to model LDS errors.The two kernels are connected with stepwise iterations to find the best calibration results.Compared with traditional methods,hand-eye experiments show that IABC reduces the calibration RMSE by about 50%.Verification experiments show that IABC reduces the measurement deviations by about 25%-50%and RMSEs within 40%.Even when the training data are obviously less than the test data,IABC performs well.Experiments demonstrate that IABC is more accurate than traditional hand-eye methods. 展开更多

Significant advancements in ultra-precision machining technology have forced a re-examination of the spindle perpendicularity errors'impact on the milled surface quality at the micro-nano scale.In this paper,a method of spindle precision adjustment is proposed to enhance surface finish quality.Sensitive errors in the machining process are identified using multi-body kinematic theory,with the milling process serving as an example.A two-degree-of-freedom(2-DOF)rotation platform is designed,optimized,and fabricated.The platform's static model is established based on elastic beam theory and verified by finite element analysis.Structural parameters are optimized via the response surface method in combination with the Pareto front.Experimental results reveal the effects of spindle speed,voltage amplitude,vibration frequency,cutting depth,and feed rate on the platform's modulation performance.The static modulation experiment shows that the perpendicularity error between the spindle and the guideway can be reduced from 92.5μrad to 0.25μrad.Finally,milling experiments show that the surface quality can be improved by 37.6%after spindle modulation. 展开更多

Carbon fiber-reinforced carbon and silicon carbide(Cf/C-SiC)composites have garnered substantial attention because of their superior mechanical properties at elevated temperatures.In the present work,the tribological properties of 2.5D Cf/C-SiC against silicon nitride under dry friction over a wide temperature range,ranging from room temperature(RT)to 800℃,are studied with a pin-on-disc tribometer,and the microstructure is characterized via a variety of methods.The results underscore that 600℃ marks a pivotal juncture where the tribological properties of Cf/C-SiC undergo a notable shift.Below 600℃,the friction coefficient clearly increases with increasing temperature,paired with minimal wear.For this temperature range,the main wear mechanisms are minor oxidation wear and slight abrasive wear.In contrast,above 600℃,a slightly lower,fluctuating plateau is observed in the friction coefficient.This is attributed to the accumulation of wear debris,the cyclical formation and breakdown of the friction film,and the softening of the friction surface.For temperatures above 600℃,the wear mechanism transitions into a state characterized by the concurrent presence of adhesive wear,abrasive wear,and severe oxidative wear.This study provides an in-depth understanding of the tribological behavior and wear mechanism of Cf/C-SiC at elevated temperatures. 展开更多

Excellent wear resistance is an important feature of orthopedic implants.However,although pure polyetheretherketone(PEEK)is outperformed by carbon fiber-reinforced PEEK(CF-PEEK)for stability and durability under laboratory conditions,it is not clear whether CF-PEEK should be preferred in all real-world applications.Results indicate that,under dipalmitoylphosphatidylcholine(DPPC)lubrication,the wear rates of PEEK are 35%-80%lower than the wear rates of CF-PEEK for different implant materials,speeds,loadings,and DPPC concentrations.Molecular dynamics calculations confirm that DPPC self-assembles on the PEEK surface to form an easily adsorbed continuous phospholipid lubricating film.In contrast,the carbon fibers on the CF-PEEK surface hinder the formation of the protective DPPC film and the CF-PEEK surface is thus subject to faster wear. 展开更多
