叶片属于特型零件,型面精度要求极高,因此,在加工过程中要严格控制其误差。分析了非线性误差产生的原因及有效估算方法,结合线性插补原理,建立了非线性运动误差估计模型以及误差补偿模型。通过 Java语言,依据VMC850F机床进行运动求解,开发了针对叶片五轴加工具有非线性误差补偿功能的专用后置处理器;并通过某叶轮的切削加工实验验证了该后置处理器的正确性和实用性。

Blade is a special type of parts,and its type face demands extreme high accuracy,therefore,its error must be strictly controlled in the machining process. The causes and effective estimation method of nonlinearity error were analyzed. Combining with linear interpolation principle,a non-linear motion error estimation model and error compensation model were established. Using Java language,the dedicated postprocessor for blade five-axis machining with a non-linear error compensation function was developed based on the VMC850F machine movement solving. The correctness and practicality of the postprocessor are verified through an impeller cut-ting experiments.
