本文研究了对镗孔尺寸误差的预报与补偿。用时间序列分析的方法,建立了尺寸误差的动态线性数学模型。这一模型在不同场合下都具有模型参数自修正的能力。计算机仿真的实践证明:在实际使用情况下,预报精度令人满意。
This paper studies the prediction and compensation of the boring hole size error. With the method of time series analysis, a dynamic linear mathematical model of size error is established. This model has the ability to self-correct model parameters on different occasions. Computer simulation shows that: in actual use, the forecast accuracy is satisfactory.
