In the machining processes, achieving good surface quality is also very important in parallel with obtaining accurate dimensions. Machining processes involve a number of process parameters which directly or indirectly influence the Surface roughness. This experimental study is working with Taguchi method for identifying the optimum values of the process planning parameters say spindle speed, feed and depth of cut for the good Surface finish of the cylindrical component during turning operation. The experimental work is designed using Taguchi’s L16 orthogonal array and carried out by turning Aluminium alloy 6061-T651 using Tungsten carbide tool. From the study, it is observed that the surface finish is improved by 42.24 %. The optimal values of machining parameters are estimated using Minitab 16 software. This paper discusses the optimal values of speed, feed and depth of cut for yielding the minimum Surface roughness of the turned product. In addition with the optimal values of the parameters, this paper presents the interactions among these three parameters.

The reason for using stir casting is to develop technology for the development of MMCs at affordable cost. The selection of Sic as reinforcement and Al as matrix isbecause of their easy availability. The practical data acquired, analyzed and optimized will beinterpreted in the light of information available in the literature and be shared with the relevant industries. The present work was mainly carried out to characterize the Sic/Al composite which was produced by reinforcing the various proportions of Sic (5, 10, and 15%) in aluminum matrix using stir casting technique. Itis noted that the volume fraction of Sic in the composite is gradually increased, the hardness and impact energy increase. However, beyond a level of 25-30 percent Sic, the results are not very consistent, and depend largely on the uniformity of distribution of Sic in the aluminum matrix.This work is focused to study the change in behavior of AA6061 aluminum alloy by adding different percentage of Sic Then tensile tests, hardness test, impact test performed on these samples which are produced by stir casting to investigatethe improved physical and mechanical properties.

The principle of the operating system utilized here is to applying the momentum to the sludge particles. Though crude oils contain a wide range of constituents, the components are mostly composed of hydrocarbons. Crude oils from different sources vary significantly and refineries are designed to process crude from particular sources. So technology seeks to avoid the sludges which forms in the tank during storage and it will be very harmful to human beings. The dilution system adopted here, to add the momentum of the crude oil particles, by applying rotary motion. The rotary motion of the spindle is achieved from couple force of incoming storage crude oil; implementation of the above method in the tank will reduce the processing cost of the sludge and to improve the bearing capacity of the tank and life.

The Main problem encountered in this is cell formation problem. The main aim is to minimize the exceptional elements. It also means reduce the amount of voids (o) inside the cell and reduce the amount of exceptional elements which is represented by numerical value of " 1 " outside the cell. Non-polynomial hardness is the main problem here which is not having the efficient capacity to solve the real sized problems. So we have to switch on to Genetic Algorithm approach. The group capability index has been improved with combined objective function of exceptional element detection.

In this work, chemically treated fibers are reinforced with polymers by hand-lay-up method, and the tensile test was carried out to determine the strength of material, bending test was used to obtain the flexural strength of composite materials. In addition hardness and impact test also carried out. Results were found that the strength of the composites tends to decrease with the amount of fiber, which indicates ineffective stress transfer between the fiber and matrix for both composite. The properties such as flexural strength, hardness and impact energy has a rapid increase in 5% of fiber fraction and no significant effect by further increasing fiber content to both polymers. For the fiber loaded samples, 5% fiber reinforced for polyester and 10% fiber reinforced polypropylene matrix had the optimum set of mechanical properties. Coir fiber reinforced polypropylene specimens yielded better mechanical properties compared to the coir fiber reinforced polyester. . It is evident that types of polymer have well influence on the mechanical properties of the chemically treated coir reinforced polymer composites. Authors propose that the bonding between the matrix and chemically treated coir fiber must be increased in order to have improved mechanical properties at higher fiber content
