In this study, the influence of cutting parameters and machining time on tool wear surface roughness was investigated in high-speed milling process Al6061 using face carbide inserts. Taguchi experimental matrix (L9) chosen to design conduct research with three input (feed rate, speed, axial depth cut). Tool (VB) (Ra) after different strokes (after 10, 30, 50 strokes) were selected as output par...

A fuzzy-logic controller (FLC) is designed to automatically adjust feed rate in order to regulate the cutting force of milling processes in a vertical machining center. The FLC has a double-loop structure, consisting of the inner PD (proportional-derivative) velocity-control loop for a feed servo and the outer fuzzylogic force-control loop. Reference cutting forces are well maintained in both n...

Aluminium composites are extensively used in several industrial applications. The production of Metal Matrix Composite (MMCs) with varying wt. % reinforcement/s leads to enhancement wear and mechanical behavior. In the present work, TiB2 constant CeO2 particulates were reinforced Al6061 alloy manufacture hybrid Al MMCs by Vortex (Stircasting) technique. Developed hotrolled at 515°C temperature....

Equal channel angular rolling (ECAR) is a severe  plastic deformation (SPD) technique which has been used to produce metal sheets with ultra-fine grain structure. In the present work, the relationships between the mechanical properties and microstructure of samples during the ECAR process have been investigated. The Rietveld method was applied to analyze the X-ray diffraction pattern and to det...

The current study focuses on the properties of dry sliding characteristics and impact strength two different aluminum alloys that were reinforced with 100 nm sized Silicon carbide (SiC) Aluminum oxide (Al2O3) ceramic particles, for improving mechanical final alloy mixing materials characteristics. Stir casting method is adopted fabricating composites, matrix being Al6061 Al7075, utilizing three...

Abstract The effect of different processing parameters consist pouring temperature and holding time on the semisolid microstructure Al6061 feedstock billet produced by direct thermal method has been investigated in present paper. In this experimental works, molten aluminium alloy 6061 was poured into a thin cylindrical copper mould at constant 660 °C held times 20 s, 40 60 s. After it reached d...
