针对超硬刀具PCBN(聚晶氮化硼)对难加工材料的车削加工过程建立数学模型;运用MATLAB软件中的遗传算法工具箱对切削参数进行优化;利用Mastercam软件对刀具加工时的路径进行优化,从而在理论和加工过程中实现了切削参数的优化。研究结果表明,当切削速度v=120.143 m/min,进给量f=0.154 mm/r时,经权重处理后的目标函数取得最小值;有效避免了加工过程出现刀具空走刀或撞刀等路径问题。
For the hard tool PCBN (polycrystalline boron nitride) on the difficult processing of materials turning process to establish a mathematical model; using MATLAB software genetic algorithm toolbox to optimize the cutting parameters; the use of Mastercam software to optimize the path of the tool processing , So as to realize the optimization of cutting parameters in theory and machining. The results show that when the cutting speed is v = 120.143 m / min and feed rate is f = 0.154 mm / r, the objective function after weighting is minimized. Path problem.
