Paper Abstract

In micromachining of aspherical surfaces the diamond tools are used in a zone extending over a certain segment. This zone is minimized in the spherical generator type machine, but it must be found and located by knowing edge quality over the entire length. Our method of verifying edge sharpness over the entire tool radius as well as the circularity (form) consists in viewing with a micro-interferometer a plunge cut trace produced in the real tool-workpiece configuration. This allows to set a partially defective tool for optimum machining conditions. One can also set for best cutting depth, because certain tool damages on the rear phase become effective only with deeper cuts. This will be illustrated. The micro-interferometer plunge cut inspection allows to detect material vibration, chatter and crossflow of material.
