Integrated Cost, Time and Quality Manufacturing Evaluation for Design Feedback

这项拨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为设计与可制造性评估的决策整合提供一种数学上合理且严谨的方法。具体而言，该工作有三个主要目标：(1)设计和可制造性评估的集成模型；(2)复杂、多轴和旋转加工零件的无模板特征方法，结合评估拟议产品质量属性的时间、成本和工艺变化的决策分析方法；(3)将制造评估与设计产品模型联系起来的反馈系统。目的是为改进设计和可制造性提出建议。这种方法是以前基于无模板特征的生成过程规划工作的扩展。本课题的意义在于集成模型考虑了设计和可制造性评价的信息化决策。利用基于区域工厂加工能力的制造特征，不受理论模板特征的约束，将重点放在加工过程上。这项工作的目标是发展理论和工具，通过这些理论和工具，组织或个人可以评估与工厂特定制造能力相关的拟议部件的产品模型。比较明确地说明了决策标准、偏好和成本。如果成功，这个灵活的模型将展示可制造性评估中的重要元素，以及如何将该评估与产品模型和设计联系起来，以调查重新设计选项。

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.
