Establishment of a supreme measurement technology for endmill cutting-edge profile as on milling-machine is indispensable to success the most precise milling work, such as die/mold and parts machining, recently. The aim of study is to develop a new measuring technique based on laser diffraction, which is called diffraction gauge method, to evaluate cutting-edge profiles of micro-endmill (φ≦500μm) with precision of better than 100 nm even though on-machine measurement. The measurement resolution was experimentally achieved to be 15 nm for a helical endmill and repeatability of ±50 nm with valid accuracy for new tools. In this article, the measurements on a sample of worn tool(φ300μm), which has curried out side milling of 4.4 m milling length on graphite with 40,000 rpm rotational speed, are presented. The experimental results verify that the diffraction gauge method is able to not only measure cutting-edge profiles of new micro endmills but also wear quantity of worn tools.
