Abstract
This paper presents an optimized determination of tool diameter, radial and axial depths of cut in end milling process. For such a purpose, an index of performance is proposed of which machining accuracy, manufacturing cost as well as machining efficiency are taken into consideration. Consequently, by means of the proportional relation to cutting force, maximum chip area which affects machined surface is analyzed with the behavior of cutting edge. Furthermore, flexural rigidity of end mill is investigated and an experiment of tool wear is carried out. Through these approaches, the index of performance is calculated and the optimum values of diameter of end mill and depths of cut are discussed.
