This study investigates optimal parameter setting in abrasive waterjet machining (AWJM) on aluminium alloy AA 6351, using taguchi based Grey Relational Analysis (GRA) is been reported. The water pressure, traverse speed and stand-off-distance were chosen as the process parameters in this study. An L 9 orthogonal matrix array is used for the experimental plan. The performance characteristics whi...

Abstract: In this paper, the economic design of MSE control chart is extended to the multivariate case. The important feature of this control chart is that it uses the target value instead of the process mean. According to Taguchi's viewpoint, any deviation from the target value represents a kind of loss. Therefore, we construct the model of economic design by considering not only the control c...

In this study, dysfunctional cooperative learning teams are identified by comparing the Taguchi “larger-thebetter” quality index for the academic achievement of students in a cooperative learning condition with that of students in an individualistic learning condition. In performing the experiments, 42 sophomore mechanical engineering students are randomly assigned to the two learning condition...
