Two Way ANOVA
A mechanical engineer is studying the thrust force developed bya drill press. He suspects that the drilling speed and the feedrate of the material are the most important factors. He selectsfour feed rates and uses a high and low drill speed chosen torepresent the extreme operating conditions. He obtains thefollowing results.
(A) | | Feed | Rate (B) | |
Drill Speed | 0.015 | 0.030 | 0.045 | 0.060 |
125 | 2.70 | 2.45 | 2.60 | 2.75 |
| 2.78 | 2.49 | 2.72 | 2.86 |

200 | 2.83 | 2.85 | 2.86 | 2.94 |
