An experiment on a surface-finishing operation of an overhead cam block auxiliary drive shaft was reported by Sirvanci and Durmaz (1993). The following is an adaption of the original experiment. The part had a target value of 75 um. The three experimental factors were type of insert (A), speed in rpm (B), and feed rate in millimeters per minute (C). A 23design was used; the (-, levels for the factors are (
