Process Model-Based Intelligent Control of Diamond Turning

该奖项旨在使钻石车削的轮廓精度和表面光洁度得到重大改进。这将通过研究和发展金刚石车削过程中的力-刀具-表面光洁度关系，并对力反馈的现有金刚石车床位置反馈系统进行补充来实现。在金刚石车床上实现快速刀具伺服系统，将使该系统能够对高速主轴振动进行校正。此外，快速刀具伺服系统与动态和静态力反馈相结合，将用于控制和改善车削过程中刀具磨损或振动时表面光洁度的恶化。钻石车削是一项对包括光学部件制造在内的各种关键行业都有重大影响的作业。光学制造中精度的提高已经达到了一个平台期，这项研究对于达到目前可行的精度是必要的。

This award is intended to enable a major improvement in contour accuracy and surface finish in diamond turning. This will be carried out by researching and developing a force-tool-surface finish relationship in diamond turning and supplementing the existing position feedback system of a diamond turning machine with force feedback. The implementation of a fast tool servo system on the diamond turning machine will enable the system to correct for high-speed spindle vibration. Further, the fast tool servo system, in combination with the dynamic and static force feedback, will be used to control and improve deterioration in surface finish as the cutting tool wears or vibrates during the turning process. Diamond turning is an operation that has a very significant impact on a variety of critical industries including the manufacture of optical components. The enhancement of accuracies in the manufacture of optics had reached a plateau and this research is necessary to achieve accuracies beyond those currently feasible.
