Research on Error Compensation of Probe for On-line Measurement System

  • 摘要: 通过分析在线测量系统测量过程中触发式测头测量结果的误差组成元素及其产生的原因,建立了测头标定的数学模型,并通过最小二乘法进行解算,提出通过对测头半径进行补偿来减小测量误差的新方法,该补偿方法综合考虑了实际测量过程中测头预行程误差、测头各向异性、测头偏心误差等影响因素,并利用双线性插值法建立测头半径补偿值与测点法矢方向之间的映射关系,来计算拟合任意法矢方向的半径补偿值。最后通过实验验证,对比补偿前后的测量结果,结果表明补偿后的测量系统测量精度有明显提高。
