Abstract
An analytical method for sensitivity studies in the determination of the optimum machining conditions for the single point turning process was previously presented by Ermer and Faria [4]. In the present paper, an analytical method for sensitivity studies in the determination of the optimum machining conditions for milling, drilling, reaming and tapping is presented, assuming that the optimizing criterion is minimum cost or maximum production rate. A nomogram is given which provides a simple and efficient way to carry out quantitative sensitivity analyses.
