--------------------------------------------------------------------------------------------------------------------------------Manufacturing of aluminium metal matrix Abstract - Metal matrix composite is one of the reliable
composites through two ways, one is solid state manufacturing and another one is liquid state manufacturing. Mostly, the liquid state processing of AMMC’s are preferred because of their simplicity and scalability. A metal matrix composite is a combination of two distinct metals to obtain a compounded material known as reinforced material. The reinforcement material is embedded into a matrix and does not serve a purely structural task, but is also used to change the physical properties such as wear resistance, friction coefficient and thermal conductivity.
sources to meet the demand on engineering materials such as high tensile strength, toughness, hardness, low density and good wear resistance. Aluminium based metal matrix composite used in the areas of aerospace and automotive industries include high performance, economic and environmental benefits. This paper deals with the prediction of machining parameters for aluminium metal matrix reinforced with 5wt% of boron carbide and 6 wt% of flyash in electrical discharge machining through taguchi method. L9 orthogonal array was created to achieve the high metal removal rate and surface roughness with desirable control factors such as current, pulse on time and pulse off time. Predicted result was evaluated by analysis of variance (ANOVA).
This work concentrated on machining aluminium based metal matrix composite reinforced with Boron Carbide (B4C) and Fly Ash by the size of 90 micron.
Key words: Metal matrix composite, Aluminium, Boron carbide, Flyash, Electrical Discharge machine, Taguchi method, Analysis of variance.
The advancement in automation and aerospace has made it possible to produce high quality industrial product. Qualities of mechanical products are predicted by poor metal removal rate and surface roughness. NonConventional machining process is optional for achieving high quality products. This paper concentrated on machining of aluminium based metal matrix composite by Electrical discharge machining (EDM) through Taguchi Method.
1. INTRODUCTION In the past few years, materials development has shifted from monolithic to composite materials for adjusting to the global need for reduced weight, specific strength and high performance in structural materials. Metal matrix composite (MMC) have been attracting in the field of aerospace and automobile industries for their excellent mechanical properties like light weight, high strength, moderate casting temperatures and other properties.
2. LITERATURE REVIEW Thambu sornakumar and marimuthu kathiresan has been evaluated the surface finish and flank wear in LM24 aluminium alloy and silicon carbide particles by CNCMilling machine. From the observations, the surface finish is increased with increase in speed and decrease of feed. High speed steel end mill cutters are used for machining process.
Now a day the need of light weight engineering materials for various engineering applications goes on increasing. To meet such demands aluminium metal matrix composite is one of the optional sources. Aluminium metal matrix composite (AMM) is mostly preferable for their excellent reliable properties such as reduced weight, easy manufacturing methods, wear resistance and corrosion resistance etc.
