摘　　要：分析了五轴数控机床非线性误差产生的原因,阐述了RTCP减小非线性误差的算法原理,基于C-A型双摆头机床结构建模并给出了一种RTCP补偿算法。针对嵌入式数控系统的特殊性,合理设计了在双核架构嵌入式数控系统中RTCP功能的实现方法。最后,在MATLAB中仿真验证了RTCP算法对于减小非线性误差的有效性。In this paper, the cause of the nonlinear error of the five -axis CNC machine is analyzed, the principle of RTCP （Rotation Tool Center Point） algorithm to reduce the nonlinear error is explained. Besides, a new RTCP compensation algorithm is proposed based on the modeling of C- A machine structure. Meanwhile, for the particularity of the embedded CNC system, the implementation method of RTCP function in the dual - kernel embedded CNC system is designed. Finally, the validity of RTCP algorithm is proved by the simulation on MATLAB.
