摘要
结构型表面因良好的表面特性被广泛应用于光学、生物以及航空航天等重要领域.提出三维振动辅助铣削制备结构型表面的方法,分析施加三维振动激励条件下的铣削加工轨迹.基于正交螺旋理论和空间矩阵变换建立三维振动辅助铣削模型,在正弦函数曲面面型上预测生成的结构型表面微结构形态.探究了振幅以及振动频率对结构型表面微结构形貌的影响规律.
Abstract
Structured surfaces are widely used in important fields such as optics,biology,and aerospace because of their good surface properties.A 3D vibration-assisted milling method is proposed for preparing structured surfaces and the milling trajectories under the applied 3D vibration excitation conditions is analyzed.A 3D vibration-assisted milling model is developed based on orthogonal helix theory and spatial matrix transformations to predict the microstructural morphology of the generated structured surfaces on sinusoidal function surface manifolds.The effects of amplitude,as well as vibration fre-quency on the microstructural morphology of structured surfaces are investigated.
