摘要
针对铣削加工中由于切削力波动造成刀具磨损加快、表面质量不佳的问题,提出基于最小切削力波动位置对数控铣削参数进行优化的方法。通过切削运动学仿真,分析不同切削深度下切削截面传递频率的变化过程。基于切削刃螺旋线投影视图模型,根据刀具几何特征参数,计算最小切削力波动位置,用于指导切削深度、切削宽度的匹配,优化数控铣削参数。基于最小切削力波动位置对数控铣削参数进行优化,可以减小切削力波动,提高表面加工质量。
Aiming at the problem of faster tool wear and poor surface quality due to the fluctuation of cutting force during milling, a method based on the minimum cutting force fluctuation position to optimize the CNC milling parameters was proposed. Through the cutting kinematics simulation, the changing history of the transmission frequency of the cutting section under different cutting depths was analyzed. Based on the projection view model of cutting edge spiral, the minimum cutting force fluctuation position was calculated according to the tool geometry characteristic parameters, which was used to guide the matching of cutting depth and cutting width, and optimize the CNC milling parameters. Optimization of CNC milling parameters based on minimum cutting force fluctuation position can reduce cutting force fluctuation and improve surfacing quality.
