Analysis, Design, and Manufacture of High Speed Composite Tool Spindles

该项目将开发设计、制造和测试在60000转/分转速下运行的丝绕复合材料主轴的方法。基于复合材料设计和先进的梁理论的分析方法将预测切削力的固有频率、稳定性和动态响应，以及可能导致过早失效的应力时间历史。作为分析设计工作的补充，复合主轴将通过长丝缠绕制造。这些主轴将进行静态弯曲和扭转测试，以及动态旋转和非旋转测试，以实验确定模态和模态振型。本研究将为利用各向异性复合材料主轴重量轻、刚度高的优点提供分析工具。这是重要的，因为高速加工是提高生产效率的一种方式时，加工兼容的精密部件。高速主轴是机床实现这些提高生产率和精度的关键部件。

9522897 Argento This project will develop methods to design, build and test filament wound composite spindles for operation at rotational speeds of 60,000 r.p.m. The analytical methods, based on composite design and advanced beam theory, will predict the natural frequencies, stability and dynamic response from cutting forces, and the time history of stresses that may lead to premature failure. Complementing this analytical design work, composite spindles will be fabricated by filament winding. These spindles will be tested statically in bending and torsion, and dynamically, both in a rotating and non-rotating manner to experimentally determine the modes and mode shapes. The impact of this research will be analysis tools to take advantage of the light weigh and high stiffness of anisotropic composite spindles. This is significant because high speed machining is a way to increase productivity when machining compliant precision components. High speed spindles are a critical component for machine tools to achieve these improvements in productivity and precision.
