Optimization of cutting parameters for milling TC4 materials with spiral corn milling cutter

针对螺旋玉米铣刀铣削TC4材料受力不均匀,加工效率低的问题,对螺旋玉米铣刀单刀片模型及切削力模型进行分析,通过AdvantEdge FEM软件进行相关的螺旋玉米立铣刀刀片结构参数,刀体参数设置,网络划分等得到螺旋玉米铣刀加工过程中的切削力及切削过程中的温度仿真图形,并以此仿真参数基础,进行验证加工。研究结果表明:对螺旋玉米铣刀铣削力分析后,能为加工TC4材料时更合理的选择切削用量,提高难加工材料的加工效率,减少刀具的磨损。

To solve the problems of spiral corn milling cutting TC4 material force inequality and low efficiency,single blade model and cutting force model of spiral corn milling cutter were both analysed in this paper.By using AdvantEdge FEM software to set the related corn mill cutter blade structure parameters,blade parameters,and network partition,etc.we got the in-process cutting force and temperature simulation figure of spiral corn milling cutter while processing,and on the basis of these simulation parameters,process verification is conducted.The result shows that the analysis of the milling force of spiral corn milling cutter may optimize the cutting parameters,improve the efficiency of difficult-to-machine materials and reduce the tool wear of the cutters while processing TC4 materials.
