Optimization of turning tool geometry parameters for thin-walled stainless steel bushing parts

  • 摘要: 在对某不锈钢薄壁套零件加工时出现的由于切削力过大造成零件加工精度难以保障的问题,其中刀具的几何参数是影响切削力大小的重要原因。研究了一种优化加工刀具前角、后角及主偏角从而减小切削力的方法,建立了切削仿真模型,计算了最大切削力,建立了刀具的几何参数与切削力的函数关系,并通过鲸鱼算法对刀具几何参数进行优化。研究结果表明,建立的函数关系较为精确,通过鲸鱼算法对刀具参数优化后,切削力减小了16.99%,对提高该零件的加工质量具有显著作用。

     

    Abstract: In the machining of a stainless steel thin-walled sleeve parts due to excessive cutting force caused by the machining accuracy of the parts difficult to guarantee the problem, where the geometric parameters of the tool is an important reason affecting the size of the cutting force. A method of optimizing the front angle, back angle and main deflection angle of the tool to reduce the cutting force is studied, a cutting simulation model is established, the maximum cutting force is calculated, the geometric parameters of the tool are established as a function of the cutting force, and the geometric parameters of the tool are optimized by the whale algorithm. The results show that the established function is more accurate and the cutting force is reduced by 16.99% after the optimization of tool parameters by the whale algorithm, which has a significant effect on improving the machining quality of the part.
