The cutting force is regarded as the main factor that influences quality of hole created in drilling carbon-fibre-reinforced plastic composites. This paper proposes a model for prediction thrust and torque generated composite materials using twist drill. In model, contact theory applied to chisel edge zone oblique considered lips have three distinct deformation regions. takes into account spindle speed, feed rate, drill diameter, point angle, nose radius, rake angle edge, web thickness,...
Introduction Chronic lower back pain (cLBP), frequently attributed to lumbar disk herniation (LDH), imposes substantial limitations on daily activities. Despite its prevalence, the neural mechanisms underlying remain incompletely elucidated. Functional magnetic resonance imaging (fMRI) emerges as a non-invasive modality extensively employed for investigating neuroplastic changes in neuroscience. In this study, task-based and resting-state fMRI methodologies are probe central of pain. Methods...
Composite/metal stacks are widely used in aerospace structures. To study the mechanism of damage generation during drilling carbon/epoxy composites and titanium alloy stacks, both traditional orbital were used. Because cutting parameters two processes different from each other, an appropriate comparing method was proposed based on analysis kinematics drilling. The results show that high temperature is main reason for composite/titanium stacks. Cutting heat generated machining conducts to...
Cutting heat generated during drilling of carbon/epoxy composites has been recognized as a factor to influence the machine quality. This research aims study damage induced by cutting drilling. A temperature-dependent experiment was carried out. The temperature specimen changed, and parameter constant in experiment. material near exit measured. Besides, quality detected, failure mode machined surface observed. results show that decrease stiffness with increasing induces Furthermore,...

Abstract Vegetation has long been recognized as an efficient way of preventing soil erosion; however, the effects plants on gravity erosion are still broadly unknown, especially under heavy rain conditions. In order to evaluate their influences erosion, a series rainfall simulation experiments were performed model loess gully sidewall, with height 1.5 m anda slope gradient 70°. The divided into two groups––bare land models (BLMs) and shrub (SLMs)––for inter‐ intragroup comparison,...
Abstract Surface chemical modification of boron nitride could enhance the compatibility with polymers and improve flame retardancy performances. In this work, double‐bond active sites were constructed on surface modified by γ‐methacryloyloxypropyl trimethoxysilane (KH570). Glycidyl methacrylate (GMA) was further grafted onto via free radical polymerization. Finally, melamine polyphosphate (MPP) bonded to ring opening reaction. This process proved be achieved infrared spectroscopy...
In convention grinding, only a portion of grits on the working surface wheel play cutting role and others produce heat by rubbing workpiece. There is not enough chip clearance in grinding with finer so that easily clogged, leading to serious detrimental effects especially dry carbon fibre-reinforced plastics (CFRP) composites. this study, new electroplated controlled abrasive cluster (CAC) proposed its performance carbon/epoxy composites investigated comparing conventional wheel. Since...
Based on the analysis of various disfigurements carbon fibre resin reinforced composites formed in drilling process, burr formation model is built up. Analysis results showed that delaminating entrance side mainly belong to Type III cracking breakage caused by torque and exit I avulsion axial force. Furthermore, two kinds methods evaluate degree for drilled workpieces are put forward reasonable parameters less or even no shown.
Heat is easy to aggregate during drilling carbon fiber epoxy (C/E) composites because of the materials’ anisotropy and low thermal conductivity. It can result in a high temperature gradient which has significant effect on quality workpiece tool wear. In this paper, field model unidirectional developed. Based finite difference method (FDM) distribution changes are simulated. Experiments measuring at exit hole carried out, results show that agreement with model.
