UltraFast Tool Servos for Nano-Surfaces

该奖项的研究目标是创造新的超快刀具伺服系统，与精密金刚石车床结合使用，以快速生产具有纳米级分辨率要求的表面。实现这一点的方法是发明基于可变磁阻原理的新型电磁致动器。该项目将开发技术，以避免与致动器的非线性问题，到目前为止，防止这种致动器被用于快速工具伺服的任何意义。 结合新型执行器，该项目将研究同时允许非常高的带宽，加速度和精度的控制算法。 这些技术将在精密金刚石车削过程中得到实验验证。如果成功，该项目将通过更有效地生产纳米表面来为社会带来重大利益，从而影响使用这些表面的新型设备的工业生产。 它还将促进新的使能技术向精密生产机器供应商的转移，通过使用早期的快速工具伺服原型，模型和实验结果作为示例问题和实验室实验来影响课程的教学，并促进本科生和研究生的培训，特别注意吸引代表性不足的群体。

The research objective of this award is the creation of new ultrafast tool servos, which are to be used in conjunction with precision diamond turning machines for the rapid production of surfaces with nanometer-scale resolution requirements. The approach to accomplishing this is to invent novel electromagnetic actuators based upon the variable reluctance principle. The project will develop techniques to avoid problems with actuator nonlinearities that have, until the present, prevented such actuators from being used with any significance in fast tool servos. In association with the novel actuators, the project will study control algorithms that allow very high bandwidth, acceleration, and accuracy simultaneously. These techniques will be experimentally proven in a precision diamond turning process.If successful, the project will have significant benefit to society by enabling more efficient production of nanosurfaces, and so impact industrial production of new classes of devices using these surfaces. It will also facilitate transfer of novel enabling technology to suppliers of precision production machines, impact the teaching of courses by using the early fast tool servo prototypes, models, and experimental results as example problems and lab experiments, and facilitate training of undergraduate and graduate students with special attention to the attraction of members of underrepresented groups.
