Cubitron II 砂輪的磨削性能研究

A study on Grinding Abilities of Cubitron II Wheel

指導教授 : 左培倫

摘要


2009年,3M公司在發表了新式磨料技術──Cubitron™ II,它打破了過去「砂輪磨料均為不規則外型」的概念,其磨料為均一大小三角形氧化鋁陶瓷,這使得它的磨削機制與傳統磨料有很明顯的不同。對磨削加工而言,它有可能帶來更高的材料移除率,並在此同時維持良好的工件表面品質。 本研究將針對Cubitron™ II磨料進行實驗。首先,驗證精密成型的三角形磨料能夠提供比起傳統氧化鋁磨料更好的加工成效,包括材料移除率、磨削力與表面粗糙度。接著再對Cubitron™ II磨料的工件施予軸向超聲振動加工,觀察其是否適用超聲輔助加工理論。最後再針對Cubitron™ II砂輪的磨耗進行實驗,嘗試預測其砂輪的使用壽命。希望透過研究判明Cubitron™ II磨料的加工優勢,以利後續的研究與發展。

並列摘要


In 2009, 3M™ Company introduced a breakthrough technology with the launch of Cubitron™ II. Comprised of uniformly sized triangles of ceramic aluminum oxide, all the cutting edges are toward the maching surface. The precision shaped grains are designed to fracture as they wear, continuously forming sharp edges. Because of these properties, Cubitron™ II is different from conventional abrasives in grinding mechanism. Bring an opportunity to enhance the quality of grinding. This research presents the grinding mechanism of Cubitron™ II. Design grinding experiment to realize the grinding process of Cubitron™ II abrasive and compare with conventional aluminum oxide grinding wheel. Then, use Cubitron™ II wheel in ultrasonic assisted grinding checking if Cubitron™ II abrasive conform ultrasonic assisted grinding theory or not. Finally, investigate the wear of Cubitron™ II wheel that help us estimate the life of wheel. The goal of this research is to identify the advantages of Cubitron™ II in grinding process that will be in favor of the follow-up research and developments.
