本文通过建模和实验方法研究了振动辅助微铣削中纹理表面的生成机制。为了解耦振动辅助铣削中刀具几何形状和运动学的影响，提出了一种基于齐次矩阵变换的表面生成模型。在此基础上，进行了一系列仿真，以深入了解各种振动参数（频率、振幅和相位差）对一维和二维振动辅助铣削中典型纹理表面生成机制的影响。此外，润湿性测试是在具有各种表面纹理形貌的机加工表面上进行的。发现鱼鳞纹理表面比具有波浪结构的表面表现出更好的润湿性。结果表明，振动辅助铣削是产生具有可控润湿性的某些表面纹理的有效方法。
This paper investigates the textured surface generation mechanism in vibration-assisted micro milling through modelling and experimental approaches. To decouple the effects of tool geometry and kinematics of vibration-assisted milling, a surface generation model based on homogenous matrices transformation is proposed. On this basis, series of simulations are performed to provide insights into the effects of various vibration parameters (frequency, amplitude and phase difference) on the generation mechanism of typical textured surfaces in 1D and 2D vibration-assisted milling. Furthermore, the wettability tests are performed on the machined surfaces with various surface texture topographies. The fish-scale textured surfaces are found to exhibit better wettability than those with wavy-structure. The results indicate that vibration-assisted milling is an effective method to generate certain surface textures with controllable wettability.
