【摘要】 通过对ＣＮＣ控制系统的分析，建立了轮廓误差的数学模型．从复杂加工曲线中抽取出典型曲线，讨论了产生轮廓误差的主要原因和外界扰动的特性，为进一步设计控制器提供了有用的结论．更多还原

【Abstract】 A contour error model has been proposed based on the analysis of control systems of CNC lathe. From the typical machining curve,the main factors and disturbance causing the contour error are discussed. The results are very useful for futher controller design.更多还原
