| 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。

| Abstract: | 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, S-shaped 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. |
