摘要
以GH4169高温合金为研究对象,通过机夹式刀具对工件进行插铣加工。在研究主轴转速、每齿进给量以及径向切深对切削力和刀具耐用度的影响以及变化规律的基础上,得到对刀具耐用度影响最大的是主轴转速,其次是每齿进给量和径向切深的结论。利用Matlab遗传算法以最大材料去除量为目标对切削参数进行优化,当n=800r/min,f_Z=0.012mm/z,a_e=3.5mm时,可以实现在较长刀具耐用度的情况下,获得最大的材料去除量。本研究对GH4169高温合金插铣加工的切削参数有一定的参考价值,可以有效降低生产成本。
The GH4169 superalloy was used as the research
object, and the workpiece was plunge-milled by a tool-clamping tool. After studying the influence of the spindle speed, feed per tooth, and radial depth of cut on the cutting force and tool life, as well as the changing rules, the spindle speed is the most important factor in the tool life, followed by the feed per tooth. The amount
and radial depth of cut conclusions. The Matlab genetic algorithm was used to optimize the cutting parameters for the maximum
material removal. When n=800r/min, Fz=0.012mm/z, and
ae=3.5mm, the maximum tool life can be achieved. The amount of material removed. This study has certain reference value for the cutting parameters of GH4169 superalloy plunge milling, which can well reduce the production cost.
