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。 Advant Edge was used to simulate the micro milling of AL6061-T6 to reveal the variation of cutting force and temperature in micro milling. The minimum cutting thickness was estimated by chip formation. Through the change of material cutting specific energy, the phenomenon of cutting scale effect in micro-cutting is analyzed. Micro-cutting slot milling experiments were carried out to analyze the machined surface and measure the cutting force, which provided an effective basis for the optimization of micro-milling machining parameters.
