Optimization of Process Parameters for Pocket Milling of Al7075 Using Response Surface Methodology

Nowadays, the high quality of surface finish is in demandto meet the market requirements. Manufacturing industry has many complex processes that vary in nature. The current paper describes the development of a model for pocket milling on Al7075 using Response Surface Methodology (RSM). This model gives mathematical relationships in terms of Cutting speed, Feed and Step Over for Follow periphery and Zigzag tool path strategies. The Surface Roughness (SR) is predicted with these relationships and compared with the measured surface roughness of the machined components. The error observed is less than 5% between predicted and measured values.
