Optimization Technique using Response Surface Method for USMW process

This study aims at optimizing the parameters of a manufacturing process. The process considered here is the ultrasonic metal welding of copper sheet and copper wire. The strength of the weld is maximized by optimizing the parameters like amplitude, welding pressure and weld time. Central Composite Design is adopted and the experiments are conducted based on the design matrix so obtained. A mathematical model is also developed for the same. Parametric optimization is done through Response Surface Methodology and Excel solver. The results obtained from experimental work are compared and validated through confirmatory experiments.
