摘要: 深孔鑽是一種高附加價值的加工方式,主要用在航太、汽車與國防工業上,其加工品質高於一般傳統的金屬加工。在過往的研究中顯示,深孔鑽的長刀桿本身具有的動態剛性較低,容易引發振動,因此若能對刀桿進行制振,將可進一步提高深孔鑽削的精度與品質。本文將設計一磁流變液減振器,利用磁流變液可改變阻尼值的特性,從刀桿上著手,針對不同的加工參數,對刀桿進行制振研究,使刀桿的振動受到抑制,進一步提升深孔加工的品質。
Deep hole drilling is a high-value-added hole making technology. It’s essential to the aviation, automobile and defense industries. Deep hole drilling’s manufacture quality is higher than conventional metal processing. Past researches revealed that the dynamic stiffness of the long shaft of deep hole drilling is lower. This study will conduct suppression of shaft vibration with an aim of further improving hole making quality. A magnetorheological fluid damper will be designed and installed to suppress the vibration in the drilling process.
