Surface Roughness and Material Removal Rate are foremost important factor in Electrical Discharge Machining (EDM). This study is done to see about how different machine parameters affect the Surface Roughness as well MRR. The material used is of Aluminium 2024 which has wide range of applications in Automotive and Aerospace Industry. In Aluminium 2000 series, constitution of Copper is the highest. The main reason for u s i n g Aluminium is its effective use in many Industry as well its abundance in nature. It can be treated with many other elements and properties can be widely changed to achieve the desirable uses. Copper electrodes are used for machining due its high electric resistance between the metals as well proper current discharge when compared to other electrodes. This work would give a glimpse of how Surface Roughness and MRR vary with Gap Voltage and Pulse On-Time. Peak current is fixed as constant value as they don't play a major role in determining the Surface Roughness and MRR. The above said parameters are varied to the requirement and the readings are noted down. Later MRR, Surface Roughness are measured and the readings are plotted in table. Graphs are plotted from the values obtained and conclusions are made from it. For higher Gap Voltage and optimum Pulse On-Time it showed greater Surface Roughness as well good MRR.

The fluid power industry is engrossed with numerous applications befitting to pumps. Concocting experimental plans for investigations on innovative pumps require meticulous drafting and candor infused veracity. But if we stay to ground reality, contemporary technological advancement must also be taken into for the design of experiments. It is through fending contemporary literature and writings, that any scholar will be able to design an innovative experimental plan. In this article, the experimental findings from an innovative centrifugal pump have been discussed. The camaraderie between the experimental plan and the experimental results has been eviscerated, introducing the concept of accentuated parameters. The camaraderie is ascribed to the accentuated parameter. It is through the selection and utilization of certain accentuated parameters; any experimental finding can be scoured. This article illustrates the use of accentuated parameters and their effect on the findings.
