10. Repeat Exercise 9 using an orthogonal experiment if the responses are y111 = 1.10 m in, y211 = 0.80 m in, y121 = 0.90 m in, y221 = 0.70 in, y112 = 1.05 m in, y212 = 1.35 m in, y122 = 1.10 m in, and y222 = 1.40 m in. Compare your results to Exercise 9 and comment on the effect of each factor on the machining process.
