摘　　要：利用Advant Edge对AL6061-T6的微铣削开展有限元仿真模拟,来揭示微铣削加工中的切削力、温度等变化规律,通过切屑的形成对最小切削厚度值进行初步的估算。通过对材料切削比能的变化分析了微切削中存在的切削尺度效应现象。开展了微切削槽铣实验,对加工表面进行分析并对切削力进行测量,为微铣加工参数的优化提供有效的依据。In order to studying the principle of cutting force and temperature in micro milling, FEA simulation has implemented to AL6061-T6 by AdvantEdge. The minimum chip thickness is preliminary estimated by the analysis of chip formation, and the size effect in micro machining is also revealed by studying the specific cutting force. The experiment of micro slotting is implemented, the cutting force is measured and the topography of machining surface is analyzed, which give the efficient basis to the optimization of micro machining parameter.
