摘要

由於受到競爭激烈的影響，產品的設計週期日趨縮短，對於零件眾多的模具而言，在無標準化的設計流程下，針對所有加工特徵進行製造規劃，既費工且費時，而且在繁多的加工方式中，電極設計不同於其他刀具設計，電極塊尺寸會因放電特徵、加工材料與放電參數等設計不同而有所差異，並在設計過程中高度仰賴工程師的經驗，但由於設計理念的差異，導致不同工程師設計手法皆不一致，使得零件需花費更多的設計時間，進行多次協調與設計變更。
為避免在產品設計完成後才發現錯誤，導致整體開發時間延宕的狀況，本研究以電腦輔助設計(Computer-Aided Design, CAD)軟體為架構進行二次開發，運用為製造而設計(Design For Manufacturability, DFM)的概念，規劃出放電加工之電極塊設計引導流程，透過特徵辨識法，將需要使用放電加工之區域，依特徵種類的不同列出訊息給使用者做參考，再將製造端之機台加工能力與材料的資訊做參數化整合後，輔助使用者快速設計出相對應的電極塊，讓經驗不足的使用者在標準化的流程中設計，確保產品設計一致性與降低設計電極塊之錯誤發生率，透過本研究之電極塊設計引導流程，能夠節省76.1%以上之設計時間，達到縮短整體開發時間的目的，進而提升產品生產效率。

Due to nowadays intense competition, the product design life cycle has become shorter. If there is no standardize design process, engineers need to make manufacture planning for every machining feature, which needs not only a lot of work and is time-consuming. What’s more in variety of processing methods, the electrode design is different from other tool design. Electrode block size will be different due to the different discharge characteristics, discharge machining materials and design parameters. The design process is highly dependent on the experience of engineers. Because of different design concept, design methods lead to different engineers are inconsistent, so the parts will need to spend more design time.
In order to avoid finding errors after the product design, resulting in an overall development time delays. This study uses a Computer-Aided Design (CAD) software as the framework for secondary development, according to the concept of Design for Manufacturability (DFM), the study integrated knowledge principle to show the different discharge areas by different features, and combine the information of machine and material, which helps users to design the electrode block. This will ensure that the unexperienced users do the correct design and reduce the errors. In the result, this study will reduce 76.1% design time averagely to reach the goal of lower manufacturing cost and shorten the overall developing time.
