Abstract
The industries involved in manufacturing of components try to fabricate components at a lower price than the competition to be profitable. The components are made using several processes to achieve the final form. Milling is one of the machining processes highly used during the machining of the components. To achieve lowest cost of production can be achieved only through experimentation and parameter optimization. The main objective of this paper is to optimize the parameters for the milling of AMMC Al7068/Rock Dust. An array of experiments was conducted using the Taguchi technique for different percentages of rock dust in the composite. Statistical analysis was used to understand the effect of the parameters on the surface finish and strength of the components. The spindle speeds are 900rpm, 1100rpm and 1200rpm. The feed charges are 120mm/min, 210mm/min and 250 mm/min. Depth of cut is zero 0.5mm and 1.0mm and 1.5mm. Taguchi analysis is utilized to identify the optimum parameter values and correlate feed, spindle speed, depth of cut and rock dust composition. Validations of the modelled equations are proved to be well within the settlement with the experimental statistics.
