Abstract

The fabrication of high-precision mold core can make the optical elements of freeform surface be mass-produced by plastic injection or glass mold pressing. However, diamond tools cannot directly cut ferrous materials due to rapid wear of tool. Therefore, the technology of ultrasonic assisted diamond turning is proposed to process the freeform surface on the die steel in this paper. The characteristics of vibration servo machining are analyzed and discussed by theoretical modeling and digital simulating. After fabricating freeform surface on die steel by this technology, the value Ra of surface roughness can be achieve to 5.905nm.
