Cutting Power in Chatter Machining

Abstract

This paper deals with a study of cutting power requirement in "Chatter Machining", a newly developed manufacturing method for producing fine short metal fibers. The relations between required cutting power and manufacturing conditions are experimentally investigated using a digital power meter. The results reveal that the cutting power is proportional to the chatter frequency of the tool and also to the square of the equivalent fiber diameter, and the amount of cutting power is found to be smaller than that of conventional cutting in the region of fiber formation. Further, it is confirmed that the specific cutting resistance derived from cutting power shows reasonable values as per the estimated value for conventional cutting.
