摘　　要：基于力学式切削力预测方法建立了面铣刀动态铣削模型,该模型充分考虑切削厚度、刀具前角和刀具后刀面磨损对铣削力的影响。在Matlab/Simulink环境下,进行了动态铣削力和刀具振动仿真及其频谱分析,并根据仿真结果对转速、齿数、刀具磨损量等影响因素进行了分析验证,该模型有利于揭示各切削参数对动态铣削力和刀具振动的影响规律,从而为实现切削加工参数优化提供理论支持。Based on mechanics method,the dynamic milling model of face milling cutter is constructed,which has taken the affect on milling force by the cutting thickness,tool rake angle and cutter flank wear into full consideration.The simulation and spec-trum analysis of dynamic milling force and cutter vibration are car-ried out under Matlab/Simulink,and the affecting factors as rotation speed,number of teeth and the wear amount of the tool has been analyzed and inspected based on the simulation result.This model is beneficial to reveal the effect rule of dynamic milling force and cutter vibration by various cutting parameters,and providing theoretical support for optimizing the cutting parameters.
