摘　　要：针对微细铣削表面形貌的各种影响因素,基于机床系统动态特性,建立了微细铣削表面形貌模型。采用响应耦合法得到铣刀的动态特性函数,并结合铣削力模型计算铣刀的动态挠度,将铣刀挠度引入微细铣削轨迹方程。设计了以主轴转速、进给速度、径向切削深度和铣削方式为主要影响因素的正交试验。通过实验结果和仿真模型分析了微细铣削对表面形貌的影响因素。分析结果表明,主轴转速、进给速度、径向切削深度和铣削方式是影响微细铣削表面形貌的最重要因素。Aiming at various influencing factors of micro milling surface topography,a micro milling surface topography model is established based on the dynamic characteristics of machine tool system.The dynamic characteristic function of milling cutter is obtained by response coupling method,and the dynamic deflection of milling cutter is calculated combined with milling force model,and the deflection of milling cutter is introduced into micro milling trajectory equation.The orthogonal test with spindle speed,feed rate,radial cutting depth and milling mode as the main influencing factors is designed.The influence factors of micro milling on surface morphology are analyzed by experimental results and simulation model.The results show that spindle speed,feed rate,radial cutting depth and milling mode are the most important factors affecting the surface morphology of micro milling.
