Polyetheretherketone (PEEK) material has attracted attentions and studies in the medical field due to its excellent properties suitable for orthopedic, dental, and implant applications. In order to acquire the needed geometrical accuracy and surface finish for individual customizations of components made of PEEK material, milling process basics for PEEK material have been studied in this paper. The influences of milling parameters on milling forces and surface roughness are discussed based on single-factor and orthogonal milling experiments. It shows that the effects of cutting parameters on cutting forces are basically in accordance with that in the classical metal cutting theory. But the effects of cutting parameters on the surface roughness are different. Also the significance sequences of the key milling parameters on milling forces and surface roughness are identified. Furthermore, a finite element simulation model to estimate the milling force is established and successfully evaluated for customized applications.

“…With the surge in the density factor along the machined surface, curtailment was ascertained in the average size of the WEDM machined Al-SiC-TiC composite sample, which indicates a surge in the residual stress factor [25,26]. Additionally, aluminum being the major phase particle, the intermetallic phases formed cause a surge in the factor of residual stress at disparate WEDM machining conditions [27][28][29][30]. As the gradient heat was high in the OWP dielectric medium, the latent heat of fusion acting on the surface induced fine grains along the surface of the machined composite.…”

“…The surface roughness factor and waviness increase was also attributed to the variation in melting temperatures of TiC (3165 • C) and Al-SiC (2643 • C), which caused erratic fine grain disorientations in the WEDM machined composite under the OWP dielectric medium. The analysis holds significance to comprehend the deviations for applications requiring high tolerance values of the composite application [29][30][31].…”

“…The presence of the residual factor (stress: compressive) aids in the formation of the passive barrier, thereby increasing the barrier potential for corrosion to occur [26]. The presence of high barrier potential elements of Al, TiC in the composite is further aided by the surge in roughness occurring in the OWP dielectric medium, causing a drop in the pitting potential for corrosion to take place [28,29]. A drop in the interatomic spacing due to the compressive residual factor causes further refinement in grain size along the surface, augmenting the passivation barrier inherently surging the corrosion resistance of the OWP dielectric WEDM sample [30]…”

The application of metal matrix composites (Al-SiC-TiC) in aerospace and defense industries have surged in the areas of hull safety, aviation fins, and closure units. The close to ideal solution for generating powdered mixture availing ball milling, for processing of a metal matrix composite of size 24 × 24 × 5.95 cm3 and composition of 75% Al, 10% SiC, and 10% TiC weight composition is 10:1 ball weight ratio, ball size of 8 mm, rotation speed of 250 rpm, and milling time of 4 h. The powdered mixture is compressed to pellet, sintered for two hours, and further silver coated in a physical vapor deposition setup to surge its electrical conductivity for ease of material removal. To obtain a perfect fit and finish, wire electrical discharge machining cycle has been carried out to machine the component under deionized water and oil + wax + paraffin dielectric mediums in 8 A peak current, 0.45 µs pulse on time, and 45 pulse off time as close to ideal solution, obtained by the technique for the order of preference by similarity to the ideal solution (TOPSIS) analysis. A surge is ascertained in kerf width, material removal rate, and surface roughness in oil + wax + paraffin environment in correlation with deionized water by 0.99–12.78%, 0.18–33.97%, and 2.15–36.86% respectively. The surface morphological study indicates a 32.28%, 42.57%, and 45.73% surge in residual compressive stress, surface roughness and corrosion resistance in oil + wax + paraffin dielectric medium in correlation to deionized water.

This study aims at analysing the microstructure and mechanical behaviour of quasicrystalline (Al 65 Cu 23 Fe 12 ) strengthened Al1070 composites by Friction Stir Processing (FSP). The composites with various volume fractions of quasicrystal are fabricated by a multipass (3 passes) Friction Stir Processing with 1200 rpm speed, 30 mm min −1 feed rate and tilt angle of 2.5°. The hardness measurement and tensile test performed in the fabricated composites divulged an increasing trend in the hardness values and Ultimate tensile strength up to a volume fraction of 8% of quasicrystals. The microstructural studies disclosed the increase in the hardness values are ascribed to the reduction in grain size due to the dynamic recrystallization and the strengthening of Al matrix by quasicrystals. Though the composites with higher volume fraction exhibited improved Ultimate tensile strength, the fractographic studies depicted there is transformation from ductile to brittle failure in those composites.
