Abstract
Aiming to machine a Sic whisker reinforced aluminum composite for the sake of high production rate and high cost efficiency. the self-propelled rotary tool was proposed and evaluated in this study. Experimental results show that the rotary tool made of carbide exhibits superior wear-resistance comparable to the diamond tool, that tool life of carbide has been extended dozens of times by rotary cutting, that the rotary tool bears neither built-up edge nor flank build-up, and that the radial thrust cutting force component of the rotary tool is 3040% lower than that of the fixed circular insert. The rotary tool is found to be a high performance cutting tool for machining of the composite.
