中文摘要 | 本研究主要條利用放電加工法對導電陶瓷材料進行加工的研究,探討放電加工之極性、放電電流、高壓輔助電流、脈衝時間、無負荷電壓及極間伺服參考電壓等加工參數對材料去除率、電極消耗率及表面粗糙度等放電加工特性的影響。並藉助田口實驗法之L18直交表及變異數分析(ANOVA),進行相關的實驗研究及實驗數據的分析。由研究的結果顯示,放電加工法對陶瓷材料的成形加工乃是十分可行的加工方式,經由本研究可以了解放電加工參數與加工特性間的關係,並得到最佳之加工參數組合水準值,建立高效率、高精度及高品質加工表面之陶瓷加工成形技術,提供工業與學術界參考。 |
英文摘要 | The development of high strength and toughness materials for special applications has led to find out the new types of ceramics. However, the ceramics properties that make them appeal to use also create a major challenge in machining due to the high hardness and strength. In machining ceramics materials, we find that it is difficult to use traditional machining since the tool wear is serious and the machining cost is too expensive. Nontraditional machining techniques such as electrical discharge machining (EDM) and laser beam machining (LBM) processes conclusively become one of the proper processes for machining ceramics. However, LBM was not applicable for machining ceramics since the equipment is excessively expensive to limit the applications. Thus, in this proposal, we adopt the EDM process to investigate the machining characteristics in ceramics materials. The machining parameters of EDM such as machining polarity, peak current, pulse duration, discharge voltage and power supply voltage were chosen to explore the machining efficiency, electrode wear rate, surface roughness and machined surface quality on ceramics materials. The purpose of this study is to confirm the feasibility and machining characteristics on ceramics materials via EDM. Furthermore, the machining technique on ceramics with high efficiency, high precision, and high quality machined surface was also established via EDM process. |
