Abstract:

In this paper, long copper fibers with different surficial roughness were fabricated on a common horizontal lathe with multi-edge tool, and were then compared with those fabricated by the drawing method. Coarse antlers were found on the surface of the copper fibers fabricated with multi-edge tool by means of SEM photographs. Moreover, some cutting experiments were performed to reveal the influence of cutting parameters on the surface structures of copper fibers. The results indicate that, as compared with the back engagement and the feed rate, the cutting speed influences the surface structure of copper fibers most greatly. It is thus concluded that low cutting speed as well as suitable back engagement and feed rate accordant to the equal diameter helps to obtain long copper fibers with coarse antlers.

Key words: rnulti-edge tool, copper fiber, antler surface, cutting parameter
