摘要

傳統上，產品設計及製程開發流程是由各設計師與工程師分別執行的。然而由於設計師與工程師各有不同的角度、觀點與經驗，在執行工作時，往往導致產品開發成為一個耗費鉅資及大量人力物力與時間的生產瓶頸。若加上設計品無法製造或組裝，更會造成時間、人力、物力及資源的極大浪費。本研究的主要目的在建立系統化、同步化之射出成形產品之設計方法及程序，並以此提一能將產品品質、可製性等因素加以考慮之同步工程環境之電腦輔助射出成形產品設計架構。並在此一架構下開發一電腦輔助射出成形產品設計系統，以幫助射出成形產品設計之合理化、同步化、並加速達成自動化之目標，以提昇產品之設計效率與品質、並降低成本。

Abstract

Conventionally, product and process development activities were performed separately and sequentially by designers and engineers with different responsibilities and expertise. Due to lack of communication among the development activities, a product may be designed quite sophistically but not manufacturable or too costly. In recent years, the concept of concurrent engineering has been proposed to overcome this problem by resolving all life cycle issues at the early design and current computer-aided design. The objective of this research is to develop a systematic and concurrent injection molding product design methodology and procedure that enable the practice of concurrent product design. A computer-based concurrent injection molding product design framework is then proposed based on this methodology. According to this framework, a feature-based design for injection molding system is developed using knowledge-based approach and object- oriented methodology. This system provides a feature-based injection molding product design tool and a moldability assessment tool to help the concurrent consideration of product quality and manufacturability in product design. The results of this research will facilitate the rationalization, concurrentization and computerization of product design and consequently improve the effectiveness of product and process development.EndProc
