摘要

研發一組螺絲牙板模具，通常要花費相當多的時間及成本在模信與試誤方法上，尤其在建構牙板模具幾何及現場試搓時更為耗時。有限元素分析運用在金屬成形製程分析上，已是足夠成熟之技術，然而，利用三維有限元素進行制程模擬分析時，模具幾何開關的建構通常需花費相當多的時間，例如螺絲搓牙之牙板建構。本研究為縮短在搓牙制程研發初期之時間及成本，成功地勝利CATIA軟體完成牙板幾何開關之自動化建構系統之開發系統建構出之牙板幾何可以立即輔助三維有限元素分析軟體進行搓牙制程模擬，開發人員只要輸入欲發跡之牙板設計參數，即可快速得到牙板幾何，并再進行模擬分析驗證，以縮短技術人員試搓、修模及矯模之時程。因些本文之主要貢獻在於成功的建立一套電腦輔助牙板幾何開關設計建構、分析與製造之整合技術，是項技術可以輔助國內螺絲業界創造業主主模具研發製造之生產模式，提高螺絲產業自主開發能力。

It is very time-and-cost consuming by using the trial-and-error methods in the development of the threading plate dies, especially in the site test. Furthermore, although 3D finite element analysis has been gradually applied and mature enough in the practical application, threading plate geometry construction always costs a lot of unproductive time. To shorten the threading process development time and cost, this research has successfully developed a threading plate geometry construction automation system based on a commercial CAD/CAM system CATIA. The developed system can be used to generate 3D threading plate die geometry for further threading process simulation; and the revision of the threading plate can be modified by adjusting the related design parameters. Therefore, the developed system can be used to reduce the threading process development time. The major contribution of this research is in the successful development of an automatic threading plate geometry construction system; and the developed system can be advantageous to enhance the threading process design of the screw production industry.
