Surface generation for Makyoh magic-mirror by end-milling with digitally functioned CNC machining center and magnetic polishing

Abstract

This paper describes fabrication of a Makyoh magic-mirror with an extremely small concavo-convex surface, which is invisible to the naked eye. The magic-mirror was fabricated by end-milling with a machining center on the rear of the workpiece after polishing. Incident light was applied to the mirror surface and the reflected light was projected on a screen. Analysis of the image on the screen allowed completion of Makyoh magic-mirror surface generation. Moreover, the integrated Makyoh magic-mirror production process on the machining center could be achieved by application of on-machine magnetic polishing.
