Selection of Optimum Parameters in Non Conventional Machining of Metal Matrix Composite
Aluminium metal matrix composites (AMMCs) are now gaining their usage in aerospace and automotive industries. Because of their inherent nature, difficult to machine, they find very little applications in other sectors. Even non traditional processes like Laser Jet Machining and Electro Discharge Machining result in significant sub surface damage to the work. In this paper, an attempt is made to...
متن کاملInvestigation into Machining Characteristics of Tri- Alumane Zirconium Particle Reinforcement in Metal Matrix Composite Using Ultrasonic Machining Process
Particle reinforced metal matrix composites (PRMMCs) are the materials that are extremely difficult to machine using conventional manufacturing method due to high tool wear caused by presence of the hard ceramic reinforcement. This paper presents details of an investigation into the machinability of TriAlumane zirconium (Al3Zr), Zirconia (ZrO2) and Silicon carbide (SiC)particulate reinforcedalu...
متن کاملPARAMETRIC OPTIMIZATION OF Al-SiC12% METAL MATRIX COMPOSITE MACHINING BY ELECTRICAL DISCHARGE MACHINE
In the present study, pure aluminium alloy is mixed with 12% SiC on weight basis to fabricate the metal matrix composite (MMC) material. The objective of this paper is to investigate the effect of process parameters such as pulse on time(Ton), peak current (Ip) and flushing pressure (Fp) on metal removal rate (MRR), tool wear rate (TWR) and surface roughness (SR) during electrical discharge mac...
