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.

9522897 Argento该项目将开发设计、制造和测试纤维缠绕复合材料主轴的方法，以便在60,000转/分的转速下运行。分析方法基于组合设计和先进的梁理论，将预测结构的固有频率、稳定性和切削力的动力响应，以及可能导致过早破坏的应力时程。作为分析设计工作的补充，复合材料主轴将通过纤维缠绕来制造。这些主轴将在旋转和非旋转两种方式下进行静态弯曲和扭转以及动态测试，以实验确定振型和振型。这项研究的影响将是分析工具，以利用各向异性复合材料主轴的轻质和高刚度。这一点意义重大，因为在加工符合要求的精密部件时，高速加工是提高生产率的一种方法。高速主轴是机床实现生产率和精度提高的关键部件。
