Optimization of process parameters using response surface methodology: A review

Response surface methodology (RSM) is used to optimize the process parameters in casting, welding and machinability studies of composite materials. Response surface methodology is commonly used to design the experiments and it minimizes the numbers of experiments for specific number of factors and its levels. It has many advantages over Taguchi method of design. Experiments are conducted as per the experimental design and the responses such as output is recorded. Analysis of variance is used to identify the factors which significantly influence the response. Regression equations are developed to predict the response and the process parameters are optimised for obtaining a specific objective function.
