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.
