Abstract
An investigation of the effect of stiffness of the machining system on tool life with different numbers of teeth in the cutter, cutting speeds, and feeds is described. A statistical analysis was used and the effects of significant factors and interactions were determined. Not only the cutting speed, feed, and number of teeth in the cutter, but also the stiffness and their interactions have a significant effect on tool life. Due to a significant effect of interactions, the effect of the stiffness of machining system depends on the number of teeth in the cutter, cutting speed and feed. A new tool life equation was developed to take this phenomenon in account. The tool life decreases with increasing the number of teeth in the cutter. The static and dynamic stiffness was measured by means of a pulse-testing method which is both simple and reliable in determining the dynamic characteristics of a machining system.
