This grant provides funding for development of time-saving tools to connect more closely design and manufacturing. The overall purpose of this research is to provide a mathematically sound and rigorous approach to the integration of decision making in design and manufacturability assessment. In particular, there are three primary objectives of the work: (1) an integrated model for design and manufacturability assessment, (2) a template-free feature methodology for complex, multi-axis and rotational machined parts combined with a decision analysis approach for assessing time, cost and process variation of quality attributes of a proposed product, and (3) a feedback system for linking manufacturing evaluation and the design product model. The objective is to make recommendations for improving design and manufacturability. This approach is an extension of previous work done in generative process planning based on template-free features. The significance of this project is that the integrated model takes into account information-based decision making in design and manufacturability assessment. By using manufacturing features based on machining capabilities of the parochial factory, and not constrained to theoretical template features, the emphasis is on the process. The goal of this work is the development of theory and tools by which an organization or individual can evaluate a product model of a proposed part in relation to the factory's specific manufacturing capabilities. The comparison explicitly states the decision-making criteria, preference and costs. If successful, this flexible model will demonstrate the important elements in manufacturability assessment and how this assessment can be linked back to the product model and design to investigate redesign options.

这笔赠款为开发节省时间的工具提供资金，以更紧密地连接设计和制造。本研究的总体目的是提供一个数学健全和严格的方法，在设计和可制造性评估的决策集成。 具体而言，这项工作有三个主要目标：（1）用于设计和可制造性评估的集成模型，（2）用于复杂、多轴和旋转加工零件的无模板特征方法，其与用于评估所提出的产品的质量属性的时间、成本和过程变化的决策分析方法相结合，以及（3）用于将制造评估与设计产品模型相关联的反馈系统。其目的是为改进设计和可制造性提出建议。这种方法是以前的工作的基础上无模板特征的生成式工艺规划的延伸。 该项目的意义在于集成模型考虑了设计和可制造性评估中基于信息的决策。通过使用基于狭隘工厂的加工能力的制造特征，而不限于理论模板特征，重点是过程。这项工作的目标是理论和工具的发展，组织或个人可以评估一个产品模型的一个拟议的一部分，工厂的具体制造能力。该比较明确地陈述了决策标准、偏好和成本。如果成功的话，这个灵活的模型将展示可制造性评估中的重要元素，以及如何将此评估与产品模型和设计联系起来，以研究重新设计选项。
