Consider the following three-factor experiment to investigate the effect of honing pressure, number of strokes and cycle time on the surface finish of automobile brake drums. Each of these factors is investigated at two levels. The honing pressure is investigated at levels of 200ps and 400 pa, the number of strokes used is 3 and 5 and the two levels of the cycle time are 3 and 5 seconds.
