Study of Low-Degree-of-Freedom Parallel Kinematics for Multi-Scale Manufacturing Applications

这项研究的目的是系统地探索和表征适用于多个长度尺度的制造应用的低自由度并联运动学方案。探索的方法将采用类型合成和已知和新方案的反转。表征将集中于方案的运动学分析，其结果将被编码到软件工具中，以帮助改进基于此类运动学方案的机床的分析技术、设计方法和实验技术。概念验证分析将涉及两个具体的应用：a)高带宽中尺度级和b)柔性生产线加工工位的低自由度级的共轭。除了解决具体的研究目标外，该项目还将开展活动，让本科生参与各种制造应用的并联运动学阶段的设计、分析和表征。此外，该项目还将通过暑期项目为未被充分代表的高中生提供体验研究的机会。在成功完成后，该项目将为高性能机床确定新的新颖的并联运动学方案。高带宽中尺度级预计将立即为用于微米和纳米技术的不断增长的扫描探头仪器家族提供高性能阶段。软件工具和分析技术将为机床设计者和建造者提供综合和分析使用并联运动学方案的新机床概念的手段。最后，未来的科学家和工程师将在先进制造机械的研发方面获得经验。

The objective of this research is the systematic exploration and characterization of low degree-of-freedom parallel kinematics schemes for manufacturing applications across multiple length scales. The approach to exploration will employ type synthesis and inversions of known and new schemes. The characterization will concentrate on kinematic analysis of the schemes, the results of which will be encoded in software tools to aid in the advancement of analysis techniques, design methodologies, and experimental techniques for machine tools based on such kinematics schemes. Proof-of-concept analysis will address two specific applications: a) high-bandwidth meso-scale stages and b) conjugation of low degree-of-freedom stages for flexible transfer line machining stations. In addition to addressing specific research goals, this project will undertake activities to involve undergraduate engineering students in the design, analysis and characterization of parallel kinematics stages for various manufacturing applications. Also, the project will provide opportunities for underrepresented high school students to experience research through summer programs.Upon successful completion, this project will have identified new and novel parallel kinematics schemes for high performance machine tools. The high-bandwidth meso-scale stages are expected to immediately contribute to high performance stages for the growing family of scanning probe instruments that are used in micro- and nano-technology. The software tools and analysis techniques will provide machine-tool designers and builders with the means to synthesize and analyze new machine-tool concepts that use parallel kinematics schemes. Finally, future scientists and engineers will have gained experience in research and development of advanced manufacturing machinery.
