This is a 23 factorial design - in other words, a complete factorial experiment with three factors, each at two levels. Hence there are eight runs in the experiment. Since complete factorial designs ...

The previous example illustrates a complete factorial experiment involving eight runs and three factors: cutting speed (SPEED), feed rate (FEED), and tool angle (ANGLE). Now, suppose two machines (A ...
