Abstract
To produce die/mold consisting of smooth curve surfaces by hale (non-rotating tool) machining, it needs simultaneous six-axes controlled machining center. Therefore, we developed a system of six-axes hale machining and that of creating NC data. We got the following results from the whole system. Firstly, we cut curve surfaces both by five-axes as well as six-axes machining center, evaluated the machined surface and cutter path. Secondly, during cutting we maintained the movement of the tool axis as small as possible so as to improve surface roughness (Ry). Finally, we succeeded to achieve Ry of curve surfaces less than 1μm.
