During the past decade, the Quick Tool-Life Testing Method has been studied. However, a generalized theory and testing method for the quantitative measurement of tool wear have not been developed yet. Among many factors to affect the tool wear, the flank wear is regarded as a main factor. In this study, the behavior of the flank wear for carbide tool was studied as a preceding step to present a simple method for Quick Tool-Life Testing, and it was found that the flank wear varies in direct proportion to cutting time, and the following general equation is obtained for the flank wear curves with respect to cutting time and velociety.
