摘要
本文在建立数控机床伺服系统的动态数学模型的基础上，分析了用数控机床加工直线和圆轨迹时所产生的轮廓误差，从而得出了一些具有重要的理论价值的结论．
This paper provides a mathematical model of dynamic of the servo system of numerical controlled machlne -tools. Based on the mathematical model, it also analyzes the contour errors, whlch are produced by numerical controlled machine - tool in prucessing the locus of the straight line and circle. The results obtained have theoretical value.
