MANUFACTURING EXPERIENCE IN A DESIGN CONTEXT ENABLED BY A SERVICE ORIENTED PLM ARCHITECTURE

摘要

An increased competition on the product development market pushes the industry to continually improve product quality and reduce product cost. There is also a trend towards considering a products life cycle aspects including environmental sustainability. The manufacturing process is a major cost driver in the product life cycle; hence, there are many initiatives to improve manufacturability and reduce production cost. Learning from earlier projects is essential to avoid recurrence of problems and is generally realized through use of concurrent engineering and design for manufacturing (DFM). Other research provides general DFM principles which state detailed guidelines for how different geometries combined with different manufacturing processes affect component quality and cost. The real competitive edge lies however in the development and application of company specific DFM principles that are based on manufacturing experiences. To do so requires an overview of and access to the collected manufacturing experiences. The aim of this paper is to point out key enablers for efficient reuse of manufacturing experience, which is considered to contribute to lower product cost and higher product quality.rnA study performed at an automotive and at an aerospace engine manufacturer pointed out the apparent need and lack of reuse of manufacturing experiences in product development. Applications supporting reuse of manufacturing experience through embedded DFM knowledge in designer's CAD system were found in the literature. The issue of integrating these applications with the enterprise environment, in order to capitalize on existing sources of manufacturing experience, is addressed with a proposed solution applying a service oriented PLM architecture. In addition, a graphical user interface visualizing the manufacturing experience in a combined product and process context was developed. The validation of these proposed and developed solutions was done through interviews and workshops. The conclusions are thatrnvisualization of manufacturing experiences in a combined product and process context provides improved understanding of how the experiences relate to each process history and that a key enabler for integration of information in heterogeneous environments is the use of standard service oriented architectures and neutral formats.
