摘　　要：对非圆曲面特殊工件外廓相切磨削的脉冲分布及三种进给动作对应脉冲的最优化频率匹配进行了研究。首先建立了特殊工件相切磨削的数学分析模型,确立了加工分段。然后求取了进给过程中x向平移、y向平移及rotz旋转所对应的脉冲数分布。最后对这三种进给动作对应脉冲的频率最优化匹配进行了设计,使得工件在保证加工精度的前提下加工时间最短,并对方案的加工误差进行了分析。程序运行结果表明了分析模型及脉冲匹配控制方案的正确性。This paper investigates the feeding pulse distribution for the external contour grinding of the special non-circular surface workpiece and meanwhile designs the optimal pulse frequency match scheme of the three feeding motions.The mathematical analysis model was firstly set up,and the grinding section setting was also obtained.Then the pulse distribution of the x-direction motion,the y-direction motion and the rot z motion was calculated.Finally,with the premise of ensuring the grinding precision,the optimal pulse frequency match scheme of these three motions was designed to minimize the grinding time.Besides,the grinding error of this method was also analyzed.The result obtained from the program verifies the correctness of the analysis model and the pulse frequency match scheme.
