Abstract
Abstract This paper aims at developing an effective methodology to find the optimum inserting conditions that maximize the pullout strength of joints produced by ultrasonic insertion process using response surface methodology (RSM) and genetic algorithm (GA). Experiments were planed as per central composite design of experiments. The second order mathematical model for pullout strength was developed using response surface methodology with pressure, inserting time and holding time as process parameters. The developed RSM model is then coupled with GA, to determine the optimal inserting conditions. The results of this study revealed that the proposed RSM – GA integration technique managed to find the optimum inserting conditions, which leads to the maximum value of inserting performance when compared to the RSM results.
