振动辅助铣削加工仿生表面研究

摘要

In order to explore the feasibility of bionic surface feature manufactured by feed direcG tion vibration assisted milling,tool and workpiece separation conditions were derived from mathematG ical calculation,and the tool path was simulated with reasonable analysis scheme.Then the results were compared with vibration assisted milling experimental surfaces and specific biological surfaces.It turns out that vibration assisted milling surfaces and specific biological surfaces have similarity in toG pography,which proves that vibration assisted milling is feasible in the field of bionic surface manuG facturing.%为探究沿进给方向施加振动辅助铣削加工仿生表面形貌的可行性，通过数学计算获得了刀具与工件分离的条件。设计了仿真分析方案，将振动辅助铣削 MATLAB 仿真刀尖轨迹与实验加工表面以及典型生物表面形貌进行了对比分析。分析结果表明，振动辅助铣削表面形貌和典型生物表面形貌具有相似性，证明了振动辅助铣削加工技术在仿生表面加工领域应用的可行性。
