项目摘要
The objective of this Small Grant for Exploratory Research (SGER)/Collaborative Research project is to merge the fields of classical decision theory and high-speed milling in order to study machining optimization in the presence of uncertainty. This will enable the mathematical rigor of decision theory to be applied to milling optimization, while incorporating models used to describe milling operations which naturally include uncertainty. The approach will be to expand prior optimization studies to include limitations imposed by process stability and part errors due to forced vibrations, in addition to the more traditionally considered tool wear, on a profit-based objective function. Probabilistic dependence between the control variables will be incorporated to capture the correlation between them. The uncertainty will then be described using a joint probability distribution for all variables and the expected utility will be maximized over the control variables. The effects of risk aversion on the optimal values of these controls will also be explored. In particular, the hyperbolic absolute risk averse (HARA) utility function, which generalizes both the logarithmic and exponential utility functions, will be used. Sensitivity to risk aversion and variance of the variable distributions on the optimal selection will also be established. If successful, this research will lead to improved selection of machining parameters at the process planning stage. This will increase machining efficiency and reduce cycle times. Another benefit of this research will be increased awareness of decision theory fundamentals within the manufacturing community (and vice versa). By presenting this research in discipline-specific conferences, the investigators will promote future interactions of this nature.
这个探索性研究(SGER)/合作研究项目的目的是合并经典决策理论和高速铣削领域,以研究存在不确定性的加工优化。这将使决策理论的数学严谨性被应用到铣削优化,同时结合用于描述铣削操作,其中自然包括不确定性的模型。该方法将扩大以前的优化研究,包括过程稳定性和部分由于强迫振动,除了传统上认为刀具磨损,对利润为基础的目标函数的错误所施加的限制。将纳入控制变量之间的概率依赖性,以获取它们之间的相关性。然后,将使用所有变量的联合概率分布来描述不确定性,并在控制变量上最大化期望效用。风险规避对这些控制的最佳值的影响也将被探讨。特别是,双曲绝对风险厌恶(HARA)效用函数,它概括了对数和指数效用函数,将被使用。还将建立对最优选择的变量分布的风险规避和方差的敏感性。如果成功,这项研究将导致在工艺规划阶段的加工参数的选择改进。这将提高加工效率并减少循环时间。这项研究的另一个好处是提高了制造界对决策理论基础的认识(反之亦然)。通过在特定学科的会议上介绍这项研究,研究人员将促进这种性质的未来互动。
