Chip-Bifurcating Criteria for Bifurcating Chip Cutting Method of Metal Fibers

Abstract

Along with the wide applications of metal fibers in many fields, more and more attentions were paid on the preparation of metal fibers. Bifurcating chip cutting (BCC) is an effective method of manufacturing slim long metal fibers with high efficiency. In this paper, the chip-bifurcating states were studied in the process of BCC. The states can be classified into four kinds of circumstances according to the experimental results: thorough chip-bifurcating, incomplete chip-bifurcating, part chip-bifurcating and chip-bifurcating entirely but sticking together. Moreover, three chip-bifurcating criteria were proposed to keep the thorough chip-bifurcating state stable. The three chip-bifurcating criteria are found in good agreement with experimental results and can be used as a practical guide for producing slim long metal fibers by BCC.
