摘　　要：系统地分析了普通车床刀架的结构特点,以多体系统理论和齐次坐标变换原理为基础,以CA6140车床为例,采用Matlab编程建立了该车床刀架系统的几何误差模型。应用人机交互的模式可以对刀架系统进行快速的几何误差建模与分析。其误差敏感性和规律分析结果可以为刀架系统的公差设计、刚度分配提供重要依据。The characteristics of cutter frame of topological structure on general purpose lathe were analyzed systematically.Based on the multi-body system theory and the homogeneous coordinate transformation principle, taking an example for CA6140 lathe, a geo-metric error model for lathe cutter frame system was established through using Matlab programming.Through using man-machine inter-active input method, geometric error modeling and analyzing on cutter frame system were quickly done on tha cutter frame system.The analysis results of error sensitivity and error regularity can be used as important basis for tolerance design and stiffness distribution on cutter frame system.
