Title: Methods and systems for chip breaking in turning applications using CNC toolpaths

Abstract

The present invention provides methods and systems for chip breaking, controlling cutting tool wear, and the like in turning, boring, and other applications, including: engaging a workpiece with a cutting tool in a feed direction along a toolpath, superimposing an oscillation in the feed direction on the toolpath, and dynamically or non-dynamically varying the oscillation superimposed in the feed direction on the toolpath such that interrupted cuts and chips of a predetermined length or less are produced. These systems take full advantage of computer numerical control (CNC) methodologies.
