A 2k experiment was designed to help a manufacturer improve the surface finish of parts produced on a milling machine. The factors and the levels considered were: Factor Spindle Speed Feed Rate Low Level 10000 rpm 0.2 mm/rev High Level 24,000 rpm 0.6 mm/rev In coded units, the direction of steepest ascent was found to be: 0.500/1 (Spindle Speed/Feed Rate) In order to follow the direction of steepest ascent, if a one unit step of 0.2 mm/rev is taken in the Feed Rate direction, what will be the change in Spindle Speed rpm (expressed in rpm, rounded to the nearest whole number)?
