【摘要】 为进一步提高凸轮磨削加工精度,针对凸轮磨削产生的升程误差进行研究,采用遗传算法对凸轮升程误差进行修正。实测凸轮升程值通过C市第一机床厂提供的软件调整相位误差,将凸轮升程误差与升程值通过小波变换获得二阶差商光顺值。最后以凸轮升程曲线二阶差商光顺值为目标,利用遗传算法对凸轮升程误差进行修正。实验仿真表明,该方法可以获得光顺的凸轮升程值。更多还原

【Abstract】 In order to improve the accuracy of the cam grinding process,the lift error of cam grinding is studied.Genetic algorithm is used to correct the cam lift error. The measured cam lift value is adjusted by the software provided by the first machine tool plant in C city. The cam lift error and the theoretical cam lift value are taken as inputs,and the two order difference values are obtained by wavelet transform. The smooth two order difference of cam lift value is taken as the objective,and the genetic algorithm is used to correct the cam lift error. The simulation experiments show that this method can obtain a smooth cam lift values.更多还原
