As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting proof before it is published in its final form. Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. Simulations show that the meshfree model is capable of predicting cutting forces as a function of the fibre orientation. Sensitivity analysis is conducted to investigate the effect of important meshfree parameters such as the domain of influence and weight function on forces. One of the strongest advantages of the proposed model is the simple and automatic set up process, as meshing for domain discretisation is not required.

“…Significant work was done to investigate the drilling of CFRP materials, including reviews completed by Panchagnula et al [ 9 ] and Lissek et al [ 10 ], outlining the significance of process monitoring to ensure hole quality. Kahwash et al highlighted the current practice of modelling the cutting process of CFRPs and the use of 2D orthogonal cutting due to its simplicity and computational advantage [ 11 ]. Liu et al from experimental results on drilling of composite laminates concluded that the variation between materials’ elastic modulus affected the drilled hole diameters [ 12 ].…”

When drilling Carbon Fibre-Reinforced Plastic (CFRP) materials, achieving acceptable hole quality is challenging while balancing productivity and tool wear. Numerical models are important tools for the optimization of drilling CFRP materials in terms of material removal rate and hole quality. In this research, a macro-Finite Element (FE) model was developed to accurately predict the effect of drill tip geometry on hole entry and exit quality. The macro-mechanical material model was developed treating the Fiber-Reinforced Plastic (FRP) as an Equivalent Homogeneous Material (EHM). To reduce computational time, a numerical analysis was performed to investigate the influence of mass scaling, bulk viscosity, friction, strain rate strengthening, and cohesive surface modelling. A consideration must be made to minimize the dynamic effects in the FE prediction. The experimental work was carried out to investigate the effect of drill tip geometry on drilling forces and hole quality and to validate the FE results. The geometry of the drills used were either double-point angle or a “candle-stick” profile. The 3D drilling model accurately predicts the thrust force and hole quality generated by the two different drills. The results highlight the improvement in predicted results with the inclusion of cohesive surface modelling. The force signature profiles between the simulated and experimental results were similar. Furthermore, the difference between the predicted thrust force and those measured were less than 9%. When drilling with a double-angle drill tip, the inter-ply damage was reduced. This trend was observed in FE prediction.

“…The use of composite materials is increasing in several industries such as automotive, aerospace and sports equipment. This may attribute to their superior properties to metallic materials such as the high strength-to-weight ratio, good impact resistance, sound mechanical properties and they are also cheaper as compared to metal products [1,2]. Polymer matrix composites (PMCs) reinforced with ceramic nanoparticles are the most widely used composites due to their low cost and ease of fabrication [3,4].However, the machining of these materials is very difficult to achieve due to the existence of the hard-ceramic phases that accelerate the wear rate of cutting tools [5].…”

In the present investigation, the influence of machining parameters during turning on the surface characteristics and material removal rate of epoxy/BN nanocomposites. The influence of machining parameters, typically, the feed rate, cutting speed, and depth-of-cut on the surface characteristics of epoxy/BN nanocomposite workpieces, typically, the surface roughness (Ra) and roundness error (Er) were evaluated. Moreover, the influence of the aforementioned machining parameters on the material removal rate of epoxy/BN nanocomposites was investigated. Empirical regression models were developed to estimate influences of the aforementioned independent variables on the MRR, Ra and Er.
