摘要: 
隨著機械工業的進步,對材料性質的要求也不斷提高,高硬度、高強度、高韌性及耐熱材料,逐漸被發展應用於特殊場合上,對於這些特殊材料已經不是一般傳統加工法所能加工,因為這些材料特性,會使一般切削刀具毀損,故使用特殊的加工方式或特殊超硬質合金刀具來製造。放電加工法就是為了這種需求下所發展出來得一種非傳統之特殊加工法。
目前,由於LCD、3C產業的大量需求,加上模具業對放電加工機及線切割放電加工機的依賴,線切割放電加工機逐漸成為產業上應用最多的特殊加工機。本篇論文以線切割放電加工機的機體結構進行構形設計與分析。
本文首先利用顏氏創新機構設計方法,藉由拓樸構造特性繪出結構合成之線切割放電加工機運動構形圖,依運動構形圖分別繪出立柱型和門柱型結構圖;再以構形特徵與性能指標做出評分表,選出得分較高之構形;最後用有限元素分析法,去分析構形之靜態變形量,經由分析整理,提出較適當的機體結構作為現實採用之參考。

The demand for material property is keeping higher and higher due to the progress of machinery industry such as material with high hardness, strength, toughness, and heat resistance properties are used in a lot special field. These materials cannot be manufactured by the traditional methods because the traditional cutting tools will be damaged by their special properties. Therefore, special process or special alloy cutting tools will be needed. A nontraditional manufacturing methodology called Electric Discharge Machining (EDM) is developed to meet this kind requirement.
Today, due to the highly demand for EDM and WEDM from LCD, 3C, and mold industries, WEDM has become the major manufacturing equipment. This thesis is focus on the structural design and analysis of WEDM.
The Yan's methodology of creative mechanism design is applied first through the topological characteristics to synthesize the kinematics figures of WEDM, followed by classified them into stand structure type and gatepost structure type. Then, structural characteristics and performance index are used to evaluate all structures. Finally, the Finite Element Method (FEM) is applied to analyze deformation and stress of structures with higher score. The suggestion for structural design of WEDM is obtained from above analysis results.
