· Experiments are designed using Taguchi method to find the optimum parameters for silica sand nanoparticles production using low speed ball milling. Orthogonal array and signaltonoise ratio are applied to study performance characteristics of machining parameters which are the ball to powder weight ratio, volume of milling jar, and rotation speed.
Multiple metrics could apply, but only a couple of them will be impactful enough to improve performance. For instance, say your organization has an objective to improve your employee training and development programs. You could measure the percentage of trained employees or training time, but neither of these correlate well with the real result you're looking for: developing peoples ...
