We examine the performance optimization of a drifter used for top-hammer drilling. The performance of the drifter is determined mainly by its percussion power, which is the product of the impact rate and impact energy. We selected design parameters influencing percussion performance with the goal of optimizing the percussion power output, and verified the validity of the drifter analysis model through a comparison with laboratory test results. The design parameters that influence the drifter's percussion performance have been selected efficiently through screening design method, and these parameters were analyzed using the Taguchi method. As a result, the robust design values against noise factor have been proposed applying the Taguchi method to selected design parameters.
