Reproduction of Engraved Pattern Using a 6-axis Control Machining Center

(In Case of “KEBORI” on a Curved Surface)

Abstract

The metal engraving technique "KEBORI" as the traditional arts and crafts was reproduced using the latest machining technology with a 6-axis control machining center. In the machining center, the 6th axis control for rotation control of the spindle was installed on a 5-axis machining center. In the previous study, the authors have attempted to reproduce engraving patterns on a flat surface and verified the effects of the method using the 6-axis control machining center and a non-rotational cutting tool. In the present paper, the authors investigated the possibility of processing engraving patterns on a curved surface, which was thought to require more complicated axes control for the machining center.
