“…The local coordinates are defined at the first point of the master segment with outward unit normal (n) and in plane unit tangent (t). As a result of the penetration, normal and tangential gap functions are defined as follows: (4) where, S u is the displacement of the slave node, and M u is the displacement of the master node, t is the out-of-plane unit tangent.…”

“…Composites are considered as difficult-to-machine materials [4]. This is mainly due to their strong anisotropy, abrasive nature of reinforcement, different behaviour of constituent materials under machining conditions and the complex failure mechanisms [4]. Modelling of machining is utilised to gain fundamental understanding of the machining process and to reduce costly trial and error at the floor shop.…”

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.

“…Source: Astakhov and Osman (1996), Mamalis et al (2005) and Taylor (1907) In the case of fibre reinforced plastic composites, their heterogeneous structure and anisotropic properties affect the material removal operations (Bhatnagar et al, 1995;Dandekar and Shin, 2012;Konig et al, 1985). The brittle nature of polymer matrices, especially of thermosets, leads the material to be fractured (Dandekar and Shin, 2012), instead of suffering a plastic deformation process as in the machining of metals and alloys (De et al, 1994;Taylor, 1907;Xiong et al, 2013). Moreover, this breakage mode combined with a worn tool, high cutting forces and machining temperatures can produce further damage around the borehole area, which could initiate a severe damage such as delamination (Liu et al, 2012).…”

“…The machining of fibre reinforced plastics became a field of study since the utilisation of these materials increased, due to their superior specific mechanical properties (Bhatnagar et al, 1995;Dandekar and Shin, 2012;Konig et al, 1985;Liu et al, 2012). Machining operations like trimming, turning, grinding, milling and drilling are not only intended to shape the part, however also to enable effective assembly processes for finished parts.…”

This work investigates the applicability of Taylor's model on the drilling of CFRP using uncoated WC-Co tools, by assessing the influence of cutting speed (V c ) on tool wear. Two different resins, possessing low and high glass transition temperatures (T g ), and two different reinforcements, high strength and high modulus woven fabrics, were combined into three different systems. Flank wear rate gradient exhibited to be more reinforcement dependent, while the actual flank wear rate showed to be sensible also to the type of resin. In terms of tool life, all CFRP systems adjusted into a power-type tool life vs. cutting speed curve through the full range of cutting speeds (1,000 RPM to 18,000 RPM). Therefore, Taylor's model can be applied to estimate the tool life in the drilling of CFRP using uncoated WC-Co tools with good accuracy. 96 J.L.

Stir casting process is the most important method in the aluminum matrix composites synthesis industry. In the stir casting process, the stability of the liquid aluminum surface and the highest shear force induced by the impellers are the two main factors for high quality of aluminum matrix composites synthesis. In this paper, a three‐dimensional CFD model validated on a water and air two‐phase flow system in a cold model was used to optimize the mixing string tank for aluminum matrix composites synthesis, coupling the volume of fluid (VOF) model, the k‐ϵ turbulence model, and the multiple reference frames (MRF) model. Important mixing parameters of the gas‐liquid two‐phase stirred tank such as rotation speed, type of baffles, and angle of rotating impellers were simulated and analyzed in detail. Varieties of speed were investigated to choose the best one. The best stirrer was chosen through analyzing the stability of liquid aluminum and shear force induced by impellers. The results showed that the optimal stirring speed was 180 rpm during studying the surface between liquid and gas. The best baffles with the lowest vortex were obtained through simulation, with dimensions of 50 mm × 20 mm × 350 mm. In order to get the lowest vortex between water and air and the strongest shear force, the blades should be installed at 15° with vertical direction.
