A new flexible process for pure titanium denture plate using incremental forming technology is being developed. Denture plate is a important dental prosthetic component of complete denture. In this research, incremental sheet metal stretch forming was applied to fabrication of pure titanium denture plates. This process, however, posed difficult problems about poor seizure resistance. In order to improve the surface quality, anodic oxide film was tested. Although the oxide film showed good seizure resistance, reproducible sliding marks were produced in a certain region. The effect of the feed rate of forming stylus and the slope of surface on the roughness was investigated systematically. The excessive feed rate increased the roughness because of deep tool marks. The small feed rate increased the roughness due to the severe sliding contact with tool. The results confirmed the existence of optimum condition in which the roughness was minimized.

采用增量成形技术，开发了一种新的纯钛义齿板柔性成形工艺。托板是全口义齿的重要修复部件。本研究将增量板材拉伸成形技术应用于纯钛托板的制造。然而，这一过程带来了关于抗癫痫性差的难题。为了提高表面质量，对阳极氧化膜进行了测试。虽然氧化膜显示出良好的抗咬合性，但在一定区域内产生可再现的滑动痕迹。系统地研究了成形针进给速度和表面坡度对粗糙度的影响。过高的进给速度会使加工表面粗糙度增大，产生较深的刀痕。小的进给速度会使工件与刀具的滑动接触严重，从而增加了工件的粗糙度。结果证实了存在使粗糙度最小的最佳条件。
