Abstract

This invention relates to machining with round cutting inserts, including a method and a cutting tool. This invention allows a cutting tool having one or more round cutting inserts, either fixed or allowed to freely rotate under the force of chip formation, to achieve higher tool life along with similar or even higher productivity. A method, and an alternate cutting tool for some applications, take advantage of the differing ways in which the instantaneous edge angle of engagement depends nonlinearly on feed and depth of cut. By running round cutting inserts at unconventionally small depths of cut and unconventionally higher feed per tooth, edge angle of engagement reduces. The invention applies to round inserts that are radially mounted to the tool body, tangentially mounted to the tool body, or in combination of both mounting styles.
