Advanced machining technologies such as ultrasonic vibration assisted machining (UAM) and laser assisted machining (LAM) were developed to enhance the machinability of high-strength materials, including nickel alloys and bulk metallic glasses. One key challenge in machining these materials is shear banding, which results in serrated chip formation and deteriorated surface quality. The shear banding mechanisms in the UAM and LAM processes are not known. The objective of this research is to quantitatively determine the critical factors causing shear banding. The outcome will provide optimum conditions to enhance the process performance without trial and error in aerospace and automotive industries.

先进的加工技术，如超声振动辅助加工（UAM）和激光辅助加工（LAM）的发展，以提高高强度材料，包括镍合金和大块金属玻璃的可加工性。加工这些材料的一个关键挑战是剪切带，这会导致锯齿状切屑形成和表面质量恶化。UAM和LAM过程中的剪切带机制尚不清楚。本研究的目的是定量地确定产生剪切带的关键因素。该结果将提供最佳条件，以提高工艺性能，而无需在航空航天和汽车工业中试错。
