depth of cut, and stepover have been employed to carry out the experimental study.

Summarizing the main features, the following conclusions could be drawn:

1. The predicted values lie very close to the experimental values, with 5% for

spindle load and 33 s for cycle time.

2. The error between the experimental values and predicted values at the opti-

mal combination of parameters for spindle load and cycle time lies within

7.8% and 6.06%, respectively.

3. From multiresponse optimization, the optimal combination of param-

eters setting is feed rate = 1100 mm/min, spindle ...
