摘　　要：以双摆头五轴数控机床为研究对象建立了仿真模型,并对其准确性进行了实验验证。然后通过仿真分析揭示了S形试件轮廓误差在试件各分区的表现规律。基于机床动态特性与S形试件轮廓误差的映射关系,可以为实际加工中五轴数控机床动态性能参数的调整、机床性能评价及加工误差的溯源和辨识提供指导依据。A simulation model was established herein based on double swing five-axis CNC machine,and the accuracy was validated.Then the variation of S-shaped specimen contour errors under different CNC machine dynamic performances were found.And based on the simulation results,Sshaped specimen was divided into areas,and the mapping relationship among contour errors and areas was found.This study provides a basis for adjusting the actual machining five-axis CNC machine dynamic performance parameters and performance evaluation of CNC machine and processing error tracing and identification.
