TITLE: Automated Manufacturability Analysis for Machined Parts
In engineering design, the increasing use of design for manufacturability is expanding the scope of traditional design activities in order to identify and eliminate manufacturing problems during the design stage. In some manufacturing domains (e.g., near-net shape manufacturing and assembly operations), the manufacturability rules can be directly expressed in terms of design attributes. In these domains, rule-based approaches have been successfully used for manufacturability analysis. However, in case of machined parts, many manufacturability rules involve parameters of machining operations. Moreover, machined parts generally can be manufactured in several alternative ways. Thus, in order to get reliable results, it is necessary to generate and evaluate alternative machining plans.
In this talk, I will describe a methodology for analyzing the manufacturability of machined parts, by systematically generating alternative machining plans for manufacturing the part, evaluating the capabilities of each machining plan to see which one best balances the need for efficient manufacturing against the need for a quality product. By providing feedback about possible manufacturing problems with the design, this research can help to speed up the evaluation of new product designs in order to decide how or whether to manufacture them. Such a capability will be useful in responding quickly to changing demands and opportunities in the marketplace.
