Question

An engineer is interested in the effects of cut- ting speed and tool geometry on the life in hours of a machine tool. Two cutting speeds and two different geometries are used. Three experimental tests are ac- complished at each of the four combinations. The data are as follows.

Answer 1

Answer:

a. Interactions and tools are significant. Speed is insignificant.

b. The interaction effect masks the effect of cutting speed.

c. The high cutting speed has longer life for tools geometry 1 and the low cutting speed has low life for tool geometry 2.
