DMI-9734914 Tu High speed machining is a technology that has the potential of drastically reducing machining time, improving product accuracy and surface finish, and eliminating some finishing processes. One of the major problems in high-speed machining is the development of spindles with sufficient reliability to afford the high machining speed. The objective of this GOALI project is to develop a high-performance spindle prototype which is inherently reliable with high forgiveness for production error, and to study issues related to its implementation to high-speed, high-reliability processes. The research tasks include: 1) Development of an electro-thermo-mechanical model of an entire motorized spindle system for design sensitivity analysis, 2) Development of an inherently reliable spindle prototype using the model and new designs, and 3) Development of a Multiple-sensor based spindle/process monitor. The project will be performed jointly by Purdue University and Cincinnati Milacron Inc. The project is expected to have significant impact on the design of next-generation, high-performance machine tools. The knowledge of spindle dynamics, thermal behavior, and process factors critical to spindle reliability obtained from the project could reduce the cost of lost production, spindle inventories, and spindle rehabilitation due to unexpected premature failures.

Tu高速加工是一种具有大幅减少加工时间、提高产品精度和表面光洁度以及消除某些精加工工艺的潜力的技术。高速加工的主要问题之一是开发具有足够可靠性的主轴以提供高加工速度。本GOALI项目的目标是开发一种高性能主轴原型，该原型具有固有的可靠性，对生产误差具有高容错性，并研究与高速，高可靠性工艺相关的问题。 研究任务包括：1）开发用于设计灵敏度分析的整个电主轴系统的电-热-机械模型，2）使用该模型和新设计开发固有可靠的主轴原型，以及3）开发基于多传感器的主轴/过程监控器。该项目将由普渡大学和辛辛那提米拉克龙公司联合执行。 该项目预计将对下一代高性能机床的设计产生重大影响。 从该项目中获得的主轴动力学、热行为和对主轴可靠性至关重要的工艺因素的知识可以减少由于意外的过早故障而造成的生产损失、主轴库存和主轴修复的成本。
